RE: PROPOSED PLANNING LAW CHANGES WITH RESPECT TO INTENSIVE LIVESTOCK OPERATIONS IN MANITOBA

Dear Ms. Mihychuk:

We congratulate you on your new portfolio and respectfully acknowledge Ms. Friesen's tenure as the former minister of Intergovernmental Affairs and her department's attempt to modernize planning law in Manitoba. We wish her well in her future endeavors.

On a second note, we appreciate Ms. Heather MacKnight's presentation given to the Hog Watch coalition a few months ago and her good will in allowing us to get our comments in past the deadline period.

Our comments will be broad in nature, as legislative language was not provided in the presentation entitled, "Planning for Livestock Operations in Manitoba - Finding Common Ground", Manitoba Intergovernmental Affairs, February 2003.

We would expect that the draft Act would be circulated to the public for further comment, prior to it being introduced into the legislature.

Our Overall Vision for Planning = Democracy

Hog Watch Manitoba envisions planning as a tool which improves on citizen's rights to self-determination. It is a democratic process, which fully maximizes citizenship and full participation. David Morris of the Institute of Local Self Reliance (Minneapolis, MN) defines citizenship as "having the inherent authority to make the rules that govern our behavior." It is a definition, which we fully support.

Local government represents the people who are directly and continuously affected by land use choices and it is also the level of government most accessible to citizens. The Manitoba Intergovernmental Affairs Discussion document, of December 2002, states that, the province may establish laws, goals and/or standards for matters of strategic importance. (environment, natural and heritage resources, public health, transportation, certain infrastructure and regional coordination) While we would agree with this principle, we point out that the province cannot take into account the varying local history, cultural, environmental and economic conditions that are critical to successful land use decisions. Local land use planning and zoning enables communities to move toward desired economic development goals while guiding development to environmentally appropriate locations. Economic development goals may vary from community to community and from region to region. This has become evident as some citizens and communities now question whether democracy and self-determination can exist when, such a basic activity as food production, is controlled largely by transnational corporations.

On this realization, community development plans must have the ability to incorporate principles which support community economic development (CED) goals such as those advanced by the Neechi Food Cooperative. This set of principles, which has become a touchstone in the CED community, has been adopted in some form by many organizations in Manitoba. Conversely, a community development plan, must allow for the rejection of any type of industrialized agricultural activity, should the community desire so.

We ask that any modification to the Planning Act enhance our vision of democracy and citizen's rights to self-determination.

In regard to "guiding development to environmentally appropriate locations", we view this process to be a crucial step or layer for proper land use planning. We are thus disappointed that both the Consultation On Sustainable Development Implementation (COSDI) report of 1999 and the Manitoba IGA Discussion Document of 2002, A Review of Manitoba's Land Use Planning Law, do not emphasize the importance of ecological planning. Ecological baseline data such as carrying capacities of the air, land and water, resource extraction limits, pollution zones or sensitive areas and buffer areas are extremely important factors to consider when a community develops a plan. It is important that higher levels of government such as Manitoba and Canada provide the capacity to maintain, update and expand this baseline ecological information. This will require additional resources to monitor, investigate, research, survey and sample our natural and biological stock. While the province has suggested that it will move towards watershed district and nutrient management planning, expand protected areas, and increase conservation districts, there is no indication as to how these ecological planning processes will be integrated with development planning. Nor is there any indication that additional human and financial resources will be put in place to carry out these endeavors.

As an example, we believe that up to 800 livestock operations currently raising hogs in the province, are not regulated, as they were not captured in the original 1994 Manure Management and Mortalities Regulation. This may represent up to two and a half million hogs produced annually without any enforcement and/or provincial knowledge of their location.

Areas of General Concern - Health, Quality of Life, Environment and Enjoyment of Property

Section 53 of the Planning Act currently establishes the steps required for applying for a conditional use relating to a livestock operation in any given municipality. Section 53(7), "Decision of Council" gives the local council the authority to decide whether that particular development meets certain criteria. In particular, Section 53(7) (b) allows the council to "approve the application if the facts presented are such as to establish,
(i) that the proposed use or feature, at the size and intensity contemplated and the proposed location, will provide a development that is necessary or desirable for, and compatible with, the neighborhood, the community and the general environment, and
(ii) that such use or feature as proposed will not be detrimental to the health, safety, convenience, or general welfare of persons residing or working in the vicinity, or injurious to property, improvements, or potential development in the vicinity, with respect to aspects including but not limited to
(A) the nature of the proposed site, including its size…
(B) the accessibility and traffic patterns for persons and vehicles…
(C) the safeguards afforded to prevent noxious or offensive emissions such as noise, glare, dust and odour, and
(D) treatment given …to such aspects as landscaping, screening…

(iii) that such use or feature as proposed will comply with the applicable provisions of the zoning by-law and the development plan

We view section 53(7) of the Planning Act as the "democratic clause" in the planning act, which, gives a community the inherent right to reject industrialized farming and food production controlled by transnational corporations. It is a clause, which should not be removed in any amendment to the Planning Act.

Section 53(7) is important in that the onus of proof must be placed in the hands of the developer. For instance, health impacts to those who work in barns have been well documented, however, limited research has been conducted in North America (especially in Canada) as to what impacts intensive livestock operations have on those who live nearby these factories. To summarize some of the independent research from the U.S., Susanna Von Essen, M.D. of the University of Nebraska summarizes some of the concerns at a recent conference in Winnipeg, sponsored by the Manitoba Government.

"There is evidence from a small number of published research studies that people living in the neighborhood of large-scale hog facilities are more likely to have a variety of medical complaints. These complaints range from respiratory problems to burning eyes, sore throats, nausea and diarrhea, fatigue, headaches and plugged ears. Some but not all of these symptoms are like those of the hog confinement workers, who receive a much more intensive exposure to the dust and odors associated with this industry. At this time, there are no published studies in which scientists have attempted to find physical evidence of negative health effects in neighbors of hog facilities. Psychological symptoms, including tension, depression and anger were more common in hog facility neighbors studied by the group of researchers that looked at psychological aspects of the neighborhood health issue. Quality of life does appear to be affected by the presence of the unpleasant odors associated with this industry. Thus, evidence is stronger that there are negative effects on emotions and on one's ability to enjoy life secondary to residing near large hog farms."

In Missouri, the Court of Appeals ruled that Linn County had the power to make additional health ordinances to enhance the public health and to prevent the entrance of dangerous diseases into the county. This was a result of the county adopting a health ordinance in 1994 with rules and regulations regarding permits needed to operate a CAFO (Concentrated Animal Feeding Operation).

This ruling is important in that it still allows a minimum standard of state control for health but it allows for local governments to raise the level of health protection. Given that limited peered reviewed independent research exists in Canada regarding the health impacts from intensive livestock operations to those citizens living in proximity to them, the precautionary principle must be exercised in the decision-making process.

The Rio Declaration from the 1992 United Nations Conference on Environment and Development declares the precautionary principle as follows:

"In order to protect the environment, the precautionary approach shall be widely used by States according to their capabilities. Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation."

Over 75 scientists from 16 countries gathered in 2001 and issued the Lowell Statement on Science and Precaution. The following is an excerpt from the full statement:

"Precautionary decision-making is consistent with sound science because of the large areas of uncertainty and even ignorance that persists in our understanding of biological systems, in the interconnectedness of organisms, and in the potential for interactive and cumulative impacts of multiple hazards. Because of these uncertainties, science will sometimes be incapable of providing clear and certain answers to important questions about potential environmental hazards. In these instances, policy decisions must be made on the basis of sound judgement, open discussion, and other public values, in addition to whatever scientific information is available. We believe that waiting for incontrovertible scientific evidence of harm before preventive action is taken can increase the risk of costly mistakes that can cause serious and irreversible harm not only to ecosystem and human health and well-being, but also to the economy."

In Manitoba, the Public Health Act, the Environment Act, and the Sustainable Development Act fail to define or incorporate the precautionary principle within their framework. Section 53 (7) of the Planning Act and the by-law making provisions of the Municipal Act (Sections 231, 232 and 233) can be viewed as the only instruments available to citizens and local governments that allow them to exercise precautionary decision-making in areas relating to land-use planning, environment and health.

And why must we take precaution? The Government of Manitoba's appointed livestock stewardship panel, recognizes the deficiencies in information within the livestock industry in this province. Some of their observations are as follows:

"… the Panel was surprised at the lack of assembled information on the distribution of the livestock industry around the province. Neither the number or location of hog barns, for example, seemed to be mapped against broad geographical characteristics on a province-wide basis, nor could the Panel easily obtain a statistical impression of the density of large barn development."

"Provincial and federal departments hold much of the data, but there are many gaps and little coordination."

"Government is hard pressed to shape policies for the future while it lacks an overview of the present."

Deficiencies are also identified in Manitoba's own Water Strategy of April 2003, which reports:

"The knowledge and management of ground water resources is incomplete. Comprehensive hydrological and ground water supply data is incomplete.
Our understanding of the long-term impacts of development, including upstream development, on water supply, needs to improve.
Our understanding of the effects of climate change on our water supply needs to improve.

And, Manitoba's Clean Environment Commission adds the following observations.

"Current environmental research and monitoring programs by the City of Winnipeg, Manitoba Conservation and Fisheries and Oceans Canada do not appear to be adequate for the long-term protection and management of the Red and Assiniboine rivers and Lake Winnipeg…Additional funding is necessary to support this initiative."

"…based on the information presented during the public hearing the Commission is not convinced by information presented by the proponents, the public or the Government of Manitoba that hog production in Manitoba is sustainable."

"The Commission is concerned that Maple Leaf Foods and the City of Brandon did not undertake a proper cumulative effects assessment of the developments as specified in Manitoba Conservation's Advice Document.

The Canadian Medical Association, goes further in their assessment of the intensive livestock industry as they ask the Minister of Health, the Honourable Anne McLellan, "to impose a moratorium on the expansion of industrial hog farms until attendant health risks are determined through scientific assessment." (CMA resolution enclosed)

Quebec, meanwhile, has decided to continue the moratorium on pork production expansion as recommended by their public consultation process, (BAPE) which took place from September 2002 to September 2003. The public hearings were to come up with recommendations for ways to have a sustainable pork production system that took into account the economic, social and environmental aspects, and to suggest models that would provide for peaceful co-existence between pork production and rural neighbors. Issues of animal welfare, feeding animal-based feed to pigs, feeding GMO corn to pigs and the protection of water supplies were all examined by the BAPE Commission. As a result of their inquiries they have recommended that the existing moratorium on pork production be extended for a year and the Minister of Environment in Quebec has agreed to follow this recommendation.

Rights to Enjoyment of Property

In 1976, the Nuisance Act was passed in the Manitoba Legislature. This legislation was in response to a Court of Queen's Bench ruling in 1973 (Lisoway v. Springfield Hog Ranch Ltd.), that ruled that anyone, who lives beside a hog factory, are allowed to sue for nuisance under common law. Lawyer and Manitoba Green Party Leader, Markus Buchart, observes that the Nuisance Act, "essentially took away citizens' right to sue any business, including a farm business, for creating an odor that is a nuisance." The Lisoway family and some of their neighbors were also successful in appealing their property taxes in 1969 on the basis that the hog barn had greatly reduced the market value of their properties.

In 1992, the government of the day, passed the Farm Practices Protection Act, which essentially defines industrialized factory farming as a normal farming practice, and continued the protection afforded to farmers from nuisance suits. It took the legal immunity for producing nuisance farm odors out of the Nuisance Act and moved it to the Farm Practices Protection Act. Described as "right-to-farm" legislation, which has swept the continent, operators of ILO's are further protected from the common law suit of nuisance. In their analysis, both Buchart and the Canadian Environmental Law Association reach similar conclusions in that citizen rights should be restored and that they should have the ability to launch civil suits for nuisance odors and loss of property value.

Extensive research from the U.S. also demonstrates that properties located near ILO's will be negatively impacted as well as detrimental to the general welfare of those persons who live close to them. John Kilpatrick, in his analysis of seven case studies performed in six different states in the U.S., determines that odor or flies from a nearby CAFO (Concentrated Animal Feeding Operation) will restrict the use and enjoyment of impaired property without compensation. Kilpatrick summarizes the case studies and concludes that,

"The amount of value loss is typically an inverse function of distance (closer properties diminish more), a function of property type (newer, nicer residences lose more), and a function of property use (farm will lose value due to diminished productivity and comparative marketability to other farm lands). While the appraisal profession has only begun to quantify the loss attributable to CAFO's, it is clear from the above case studies that diminished marketability, loss of use and enjoyment, and loss of exclusivity can result in a diminishment ranging from 50% to nearly 90% of otherwise unimpaired value."

Proposed Planning Act Changes

The "Planning for Livestock Operations in Manitoba" presentation by Ms. MacKnight states that its' overall intent for enhanced land use decision-making for ILO's, is:

"To create a stronger land use policy and regulatory framework for livestock operations that will lead to continued diversification of the agricultural industry in balance with the resources, environment and community interests."

The power-point presentation adds that this "New approach should address problems of:

- Livestock Operations being rejected without technical basis, even in Agricultural zones.
- Municipalities setting more stringent technical requirements that engineering, planning or agricultural professionals recommend or Province requires in law/regulation.
- Unnecessary and increased costs to all parties."

Hog Watch Manitoba strongly rejects the government's design on expanding the number of intensive livestock operations in this province in the name of diversification. In fact, current government policy and laws have enabled the hog industry to become extremely concentrated and controlled by a few large corporations. In the United States, five firms control about 65 percent of the daily kill capacity. In Canada, the top four processors accounted for 61 percent of the average daily hog slaughter in 2001.

Agriculture and Agri-food Canada admits to this problem in their Medium Term Policy Baseline report, which reports that, "Many parts of the agri-food sector are experiencing an accelerated rate of industry concentration, through-out the food chain. This global phenomenon is raising concerns over market power. It has reached a level…that some players wonder whether the market power that may be the outcome, may be partially responsible for the farm income crisis."

Figures from Manitoba verify this alarming trend. Manitoba's hog industry, in terms of production from the two-year period of 2000 and 2001, grew by thirty per cent, an unprecedented growth rate in this continent. Meanwhile, Statistics Canada reports that in 2001 hog production increased sharply between 1991 and 2001 and that Manitoba leads the nation in having 30% of Canadian pigs on very large operations. In this same time period, Manitoba Agriculture and Food reports that, "Swine became Manitoba's most valuable agricultural commodity in 2001 with production exceeding 6.35 million head, valued at a record $860 million." However, they add that, "82% (of the total 1,668 hog farms in Manitoba) of the hogs that went to market came from 11% of the producers." As of October 2002, Maple Leaf Foods and its subsidiary, Elite Swine moved to being the fifth largest pork producer in North America, having a sow base of 105,000 animals with a yearly production capability of 2.5 million pigs. Only Smithfield Foods, Premium Standard Farms, Seaboard Farms, and Prestage Farms can boast having a larger sow
herd.

Dr. Peter Stonehouse, of the University of Guelph, summarizes the impacts the industrialized agri-food sector, have had. "The gainers have been food consumers (cost-wise and convenience-wise) and large agri-business corporations that are seeing their profits and market shares expand. The losers include the majority of farmers, who are increasingly merely managers for agri-business corporate bosses, consumers of nature, particularly of natural habitat and bio-diversity, many flora and fauna species, and, domesticated livestock species." It should be noted, that another gainer in Manitoba and Canada has been the banking and lending institutional sector, as farm debt, which is outstanding, amounted to over $4 billion dollars in 2001, an increase of 43% from five years ago.

As we have stated in the past, we reject the government's intent to prohibit any municipality or planning district the ability to raise the level of protection and set more stringent technical requirements above the minimal thresholds set by the province. In Minnesota for example, their state legislature specifically confirmed county's authority to adopt feedlot standards that are more stringent than the state standards (Minnesota Statute 116.07, subd 7(k)).

Recent court rulings in Manitoba confirm this right. In Grenier v. R.M. of Piney, the court ruled that,

"Piney had the right to pass by-laws 15/99 and 26/02 by virtue of ss. 231, 232 and 233 of the Municipal Act, and the applicant's (Grenier) common law rights, while not denied, are accordingly limited.

Sections 232 and 233 of the Municipal Act confer jurisdiction on Piney's council to pass the two by-laws. Its authority emanates from these sections, conferring generally on municipalities the right to legislate and administer standards for businesses and property in respect of safety, health and improvements of and incidental to land use."

In 4500911 Manitoba Ltd. v. R.M. of Stuartburn, a similar decision was attained when an intensive livestock operator took the municipality to court on it's by-law regarding livestock operations. The judge makes the observation that:

"While some aspects of by-law #036/2001 have the attributes of a zoning by-law, I am satisfied that the purpose of the by-law is to regulate intensive livestock operations. This is authorized by the (Municipal) Act, both under the general welfare provisions in s. 232(1)(a): the safety, health, and protection and well-being of people, and the safety and protection of property; and s. 232(1)(c): activities on private land (where the activity is or in the opinion of Council could become a nuisance), as well as the authority in 232(2) to regulate or to provide for a system of licenses, permits or approvals.

As to the argument that the Municipality has no authority to designate an activity a public nuisance, s. 233(d) of the Act expressly gives authority to a municipality to regulate activities or things that in the opinion of the council are or could be a nuisance."

Both judgements make reference to the Supreme Court of Canada decision (Spraytech v. Town of Hudson) which ruled that the town had the authority to regulate the use of lawn care products through it's by-law making process. As, was stated by J. L'Heureux-Dube;

"courts should respect the responsibility of elected municipal bodies to serve the communities to whom they are accountable and should avoid substituting their views for what is best for their citizenry."

In this context, we question the intent of developing a "livestock operation policy" within a development plan by-law. It is our view, and it appears that of the courts of Manitoba and Canada, that municipalities, have the legal right to govern intensive livestock operations through the by-law making provisions of the Municipal Act. This by-law could include provisions for:

" limits on the number of animal units allowed per specified amount of land
" limits on total size of operation or allowable animal units within an area
" technology based requirements such as bio-filters, manure storage covers, earthen manure liners, treatment of waste (aerobic/anaerobic)
" exclusion or total banning of liquid manure systems or requirements for straw based production methods
" posting of environmental or performance bonds for site closure, rehabilitation and potential environmental accidents
" monitoring air and water contaminants and land contaminants above and beyond minimal requirements of the provincial manure management regulation
" additional costs and fees associated for providing additional monitoring/enforcement and oversight
" requirements for permitting ILO's as a conditional use (ie, animal unit threshold for triggering a public hearing)
" setback and separation distances above and beyond what the minimal guidelines require

If a community decides that it favors intensive livestock operations and proceeds to develop or amend an intensive livestock by-law under sections 231, 232 and 232 of the Municipal Act, then a livestock operational policy may be warranted under the Planning Act. It is at this time that a community can then review its development plan by-law and determine as to where they want to site these operations through zoning.

Hog Watch Manitoba denounces the notion put forth by the Intergovernmental Affair's power-point presentation, that local governments, acting on behalf of their citizens, can be denied the opportunity to reject an intensive livestock operation without technical basis. We reiterate our view, that local land use planning, including development planning and zoning, and precautionary decision-making should be a democratic process, involving full citizen participation and not be made to be predictable and timely for the convenience of industrial expansion. Again, we stress that a municipality has the right to reject this type of development and/or regulate it through the Municipal Act. Local communities and planning districts have the democratic right to reject an industry that, for the most part, is controlled by large corporations and concentrated in the hands of the few.

It is our opinion that the proposed change of removing the conditional use process and establishing standardized set back distances and siting requirements codify industrialized agriculture and specifically, hog factories and further downloads areas of provincial and federal responsibility, such as health and environment, to municipal governments. Set back and separation distances and siting of intensive livestock operations should be governed by the Public Health Act and/or Environment Act. (We however support the need for a municipality or planning district to provide their citizenry with a venue to decide whether or not an ILO should proceed, even if it is situated in a permitted use agricultural zone).

In a previous letter to Mr. Ashton, then Minister of Conservation, (complete letter enclosed) we expressed outrage, that the barns themselves are not regulated under the Environment Act. This exemption is discriminatory as the barns emit hazardous pollutants such as hydrogen sulfide, ammonia, methane, odorous compounds and particulate matter, which at certain concentrations, impacts peoples' health and the environment. There are no air quality standards applied to the intensive livestock industry in Manitoba. Yet, in the absence of scientific evidence, the intent of the Planning Act amendment is to establish a regulation, which will standardize the separation and set-back distances of manure storage structures and animal housing structures to places where people work, live and play.

A recent study prepared for the Manitoba Livestock Manure Management Initiative (MLMMI) reports that under certain conditions, odor plumes from livestock operations can travel up to five to six kilometers. Another study prepared for the MLMMI, which measured odors from hog operations in Manitoba, concluded that there was a positive correlation between the odor level and the H2S (hydrogen sulfide) concentration for both barn exhaust and lagoon odors. Farm average H2S levels from the barn exhaust varied from 148 to 927 parts per billion.

The study also cites work done in Minnesota, by Jacobson et al. (1999) that these concentrations are similar to those recorded in Minnesota hog barns, ranging from 9 to 1156 parts per billion. Both reports, however, fail to measure odors and H2S downwind from the immediate source (lagoon, barn exhaust and manure application) and suggest that further research should be conducted.

What is alarming however, is that the Province of Manitoba has already recognized hydrogen sulfide as being acutely and chronically toxic to human health and have set guidelines for maximum tolerable, maximum acceptable and maximum desirable levels of concentrations. They have even gone further and just recently, amended the Drilling and Production Regulation (MR 116/2001) under the Oil and Gas Act to regulate acceptable concentrations of H2S. Schedule G of the regulation states:

"1. The concentration of hydrogen sulfide beyond a well or battery site shall not exceed either of the following levels:
a) one hour average - 15 micrograms per cubic metre/11 parts per billion;
b) 24 hour average - 5 micrograms per cubic metre/4 parts per billion."

Manitoba air quality guidelines also exist for ammonia and maximum acceptable levels of concentration are set at 200 parts per billion.

Environmental Canada has declared ammonia to be toxic in the aquatic environment as defined in Section 64 of the Canadian Environmental Protection Act (CEPA 1999) and requirements for control through pollution prevention planning are forthcoming. However, there has been no indication to date that air borne emissions of ammonia will be scheduled into CEPA over the near future. Yet, Environment Canada has identified agricultural operations and the fertilizer industry as the largest contributors of ammonia into the air with each contributing 474,000 and 12,000 tonnes/year respectively.

It is clearly evident that the intensive livestock industry's exemption from environmental and health legislation is discriminatory and those citizen's who live in proximity to large intensive hog barn operations, will suffer and currently are suffering the consequences.

In mid-June of 2001, Governor Tom Vilsack of Iowa, which is North America's leading hog producing jurisdiction, instructed the University of Iowa and Iowa State University to address the public health and environmental impacts of concentrated animal feeding operations (CAFO's). Involving over 40 scientists, most at the PhD level, their groundbreaking report is one of the most advanced reviews of current research and literature in North America.

Their human health effects chapter concludes:

"Numerous occupational studies have documented significant increases in respiratory disease and other respiratory health effects, including CAFO-related deaths, acute and chronic respiratory diseases and associated symptoms and acute loses in exposure-related lung function and progressive respiratory impairment, among those who work in CAFO's. However, it is recognized that the CAFO workforce is generally healthy, while those in the general community, including children, the elderly, those with chronic impairments such as pre-existing asthma or chronic obstructive pulmonary disease, are expected to be much more susceptible to CAFO exposures. There is experimental and epidemiological evidence that very low levels of exposures to ammonia and hydrogen sulfide, known to be ambient air toxic gases arising from CAFO's, may result in adverse health effects among healthy volunteers and community residents. While limited in number and scope, the currently published, peer reviewed, community based studies of adverse health affects associated with CAFO exposures find an increased prevalence of similar symptom patterns, especially respiratory symptoms, and similar indicators of reduced quality of life. Taken together with other experimental and epidemiological observations of adverse health effects observed with low levels of exposures to chemical components (ammonia, hydrogen sulfide) of CAFO emissions, these findings support a conclusion that CAFO air emissions constitute a public health hazard, deserving of public health precautions as well as larger, well controlled, population-based studies to more fully ascertain adverse health outcomes and their impact on community health services."


The Iowa Study Group further recommends that:

"hydrogen sulfide, measured at the CAFO property line, not exceed 70 parts per billion (ppb) for a 1-hour time-weighted average (TWA) period and the concentration at a residence or public use area shall not exceed 15 ppb, measured in the same manner at the property line measurement.

"Ammonia, measured at the CAFO property line, not exceed 500 ppb for a 1-hour TWA period and the concentration at a residence or public use area shall not exceed 150 ppb, measured in the same manner as the property line measurement."

On top of regulating hydrogen sulfide and ammonia, the Iowa Study groups recommends regulating odor and offer two opinions for the Iowa State government to consider.

Global Concerns

Other health and environmental impacts relating to intensive livestock operations, which have received minimal regulatory and policy oversight in Manitoba and Canada, include the overuse of antibiotics leading to antibiotic resistance and emissions of greenhouse gases.

Antibiotics

Mounting evidence is confirming the view, long held in the public health community, that antibiotic use in animals can substantially reduce the efficacy of the human antibiotic arsenal. The Union of Concerned Scientists report that important antibiotics used for human medicines, (tetracycline, penicillin, erythromycin and streptogramins) are used extensively in the absence of disease for nontherapeutic purposes (growth promoters) in today's livestock production. They estimate that every year livestock producers in the United States use 24.6 million pounds of antimicrobials in the absence of disease for nontherapeutic purposes. (10.3 million pounds in hogs, 10.5 million pounds in poultry and 3.7 million pounds in cattle) Of that 24.6 million pounds, approximately 13.5 million pounds have been prohibited in the European Union as they have been classified as important to human use. Their research also suggests that 8 times more antimicrobials are used for nontherapeutic purposes in the three major livestock sectors than in human medicine.

The Iowa Study Group reached a similar conclusion in their review of the literature in that the sub-therapeutic use of antibiotics in food producing animals (in the form of medicated feed) has been identified as the key factor in the development of resistance among food borne pathogens.

This and other mounting evidence, has lead the American Medical Association to pass a resolution to,

"…oppose the use of antimicrobials at nontherapeutic levels in agriculture, or as pesticides or growth promoters, and urges that nontherapeutic use in animals of antimicrobials (that are also used in humans) should be terminated or phased out…"

Similar findings are now surfacing in Canada. A report prepared for Health Canada by the Advisory Committee on Animal Uses of Antimicrobials and Impact on Resistance and Human Health highlight several points of concern with regard to uses of antimicrobial drugs in food animals.

"There are several points of concern with regard to resistance. First, most of the classes of drugs used in animals are also used in humans. Second, some of these are registered for use in feed as growth promoters or prophylactics. Third, some antimicrobials used in humans are administered routinely to large numbers of animals for treatment, prophylaxis or growth promotion. Such routine use is of special resistance concern because of the numbers of animals involved. Fourth, modern production methods dictate that even therapeutic treatments in some types of animals necessarily involve treatment of entire groups of animals through feed or water. This effectively increases the potential exposure to resistance selection pressure. Fifth, some drugs are registered for two or more of the following categories: growth promoters/improved feed efficiency; disease control/prophylaxis, or therapy. This could increase resistance selection pressure, eventually compromising efficacy in one or another category."

The Advisory Committee issued 38 specific recommendations in their report and came to the general conclusion that,

"…antimicrobial resistance is an important problem for both human and animal health…and …that these problems warrants changes to the ways that antimicrobials are regulated, distributed and used in animals. These changes include:
- consideration of resistance risks as a part of the regulatory review process for new and existing antimicrobials;
- adoption of prescription only availability;
- closure of own-use and imported in bulk loopholes;
- development of an improved extra-label policy;
- rapid phasing out of growth promoters that select for resistance in humans; and,
- development of surveillance systems for antimicrobial use and resistance."

Greenhouse Gas Emissions

The Manitoba Government released its Climate Change Action Plan in June of 2002. In that report, they describe some of the potential impacts relating to climate change in this region of the continent which includes, earlier spring runoff, low summer water flows and increased occurrence of drought conditions which would increase pollution levels in lakes and rivers. Some of these impacts have already manifested as Lake Winnipeg, a giant reservoir for Manitoba Hydro, is witnessing water levels corresponding to the drought of the late 1930's. Beaches were closed this past summer due to high counts of bacteria and microcystin, a toxin released from blue-green algae. Increased growth of blue-green algae in Lake Winnipeg is a result of excessive quantities of phosphorus ending up in our surface waters. Phosphorus is a constituent of human and animal waste.

Canada's ratification of the Kyoto Agreement along with Manitoba's endorsement requires a 6 per cent reduction of greenhouse gas emissions from 1990 levels by 2012. At 33%, the agricultural sector in Manitoba has been identified as the largest sector contributor of greenhouse gas emissions. Manure stored in lagoons and applied on the land are a significant source of methane emissions, as it decomposes in the absence of oxygen. Methane is 21 times more potent at trapping heat than carbon dioxide and scientists have estimated that methane concentrations in the atmosphere are now at their highest levels in 420,000 years.

It has been predicted that if Maple Leaf Foods proceeded to a second shift at their slaughterhouse plant in Brandon, the increase in hog production alone would produce an additional 50 kilotonnes of carbon dioxide equivalent per year.

Manitoba's Climate Change Action Plan is unclear as to how and if emission reductions will take place in the hog industry. The Plan suggests that, "a series of targeted measures with agriculture and other sectors, cost shared with the federal government, could offer emission reductions and sequestration or sinks credits of about 4.5 Mt (4,500 kilotonnes) per year." Manitoba's recent signing of the Federal government's Agricultural Policy Framework (APF) provides one possible venue for voluntary action where support will be provided to develop and implement environmental farms plans as well as incentive programs to adopt environmentally beneficial actions. Section 24.1.3 of the APF identifies the protection of the health of the air and atmosphere as a common goal with key priority areas being particulate emissions, odors, and emissions of gasses that contribute to global warming.

A Stronger Regulatory Framework

If the Manitoba and Canadian federal government's were serious about developing a stronger regulatory framework, greater burden wouldn't be placed on the lowest level of government to deal with the controversial issue of siting large scale industrialized factory farms.

The City of Ottawa's Medical Officer of Health recently examined other legislative approaches in other jurisdictions dealing with intensive hog farms. Of the regulatory systems that he examined, he concludes that the Canadian system is the most decentralized and that the federal departments of Agriculture and Agri-Food and Environment have played a very limited role, if any, in managing issues surrounding intensive livestock operations. He states that this is in contrast to Europe, where regulation of intensive livestock operations is addressed at the most senior level of government, the European Union and that the US Environmental Protection Agency establishes a baseline for state and municipal regulators to achieve in the US. He suggests that, "in Canada, the provinces have taken substantially different approaches to regulating intensive livestock operations, resulting in regulatory disharmony between the provinces and an opportunity for the federal government to provide national leadership on the issue."

Environmental Defence Canada (EDC) reached a similar conclusion as their research concludes that "there is much evidence to suggest that ILO's are a threat to public health and the environment; however, the Canadian federal government still has no direct regulations for ILO's." EDC calls for a national moratorium on all factory farms until:

1) the federal government establishes standards for factory farms that protect human health and the environment (including minimum separation distances that prevent manure from entering water bodies, manure management plans that prevent over-application of manure, minimum separation distances that prevent noxious gases from harming residents and best available technology standards for manure storage);
2) the federal government bans all non-medicinal uses of veterinary drugs and growth hormones;
3) factory farms are subject to the National Pollutant Release Inventory - to report their manure production, land application, air pollution, and water pollution;
4) the approval process for factory farms must be open and transparent. Citizens must have access to the decision-making process through financial and technical resources; and,
5) the federal government should pass Bill C-15B, legislation to update the Criminal Code concerning cruelty to animals.

Dr. Eva Pip of the University of Winnipeg summarizes the changes that are required to make livestock production environmentally and socially compatible.

"The change that is necessary must encompass a staggeringly large array of issues: we must reformulate not only our laws (federal, provincial and municipal), we must address out monitoring and enforcement problems, our assessment and approval mechanisms, our humane standards, our health care system, our food inspection, our trade relations, and our vision for the future of Manitoba as a whole, if we truly wish to be "sustainable", and not simply use this word as a meaningless and trendy buzzword. One cannot simply revise a few regulations and hope that the entire system will reform."


Recommendations

At this time in writing, Manitoba's pig production is estimated to be at 7 million hogs per year. The province's slaughter capacity, provided that Maple Leaf and the City of Brandon are granted an environmental license to expand to a second shift, would be 6.5 million pigs. (ie, 4.5 million Maple Leaf, 1 million Springhill, 1 million Best Brands) This slaughter capacity also assumes that the financially troubled smaller plants of Springhill Farms and Best Brand Meats remain in business. We note that Manitoba, and in particular the Maple Leaf slaughterhouse, imports approximately another 900,000 market pigs a year into the province. Of the 7 million hogs produced, Manitoba producers also export approximately 3 million to the US. (1 million market hogs, 2 million weaners)

Given that excess pig production capacity currently exists in Manitoba, even with a proposed second shift at the Maple Leaf slaughterhouse, we recommend that a moratorium be declared on the expansion of all new liquid manure systems in Manitoba. Furthermore, if finishing barns are to be built in the province, they should be straw-based systems.

Federal Responsibility

" The sub-therapeutic use of antibiotics in the livestock industry should be prohibited.
" The Federal Canada Water Act must be modernized and include nation wide enforceable water quality standards.
" Toxic emissions from ILO's should be regulated under the Canadian Environmental Protection Act.
" Canada should introduce a Federal Clean Air Act, which would regulate air quality standards.
" ILO's should be subject to the National Release Pollutant Inventory and be made to report their release of pollutants.
" Setback distances and siting of ILO's must be based on health considerations through Federal and Provincial Health legislation.
" Anti-trust legislation in Canada must be improved to prohibit the concentration of ownership in the meatpacking industry.

Provincial Responsibility

" ILO's must be defined under the Environment Act, which would include environmental assessments of larger operations (those over 250 animal units).
" Citizens must be given back their right to sue operators for nuisance.
" Single desk marketing of hogs must be given back to producers.
" Agricultural workers must be included within the Employment Standards Code.
" Workers compensation coverage for agricultural workers must be made mandatory.
" Conflict of Interest legislation must be improved for municipally elected officials, as well as Members of the Legislature.
" Anti-corporate farm legislation should be introduced in Manitoba.
" Whistle blower legislation should be provided to all workers in Manitoba.
" Improvements must be made to freedom of information legislation.
" The mandatory check-off for pork producers should be repealed and replaced with an environmental levy to enhance Manitoba's monitoring, research and enforcement capacity.

Planning Act recommendations

" The moratorium should remain in effect until all municipalities and planning districts consult their citizens and develop an ILO by-law under the Municipal Act and then proceed to amend their development plan and zoning by-law under the Planning Act.
" The Technical Review Process should be removed from the Planning Act and replaced with Environmental Assessment under the Environment Act for ILO's over 250 animal units.
" The Conditional Use decision-making process of the Planning Act should remain intact.
" Municipalities and planning districts must maintain the right to develop by-laws governing ILO's under the Municipal Act.
" Municipalities/Planning Districts must maintain the right to raise the level of protection for health, enjoyment of property and environment and be able to set more stringent technical requirements.
" The enforcement provisions of the Planning Act require vast improvements.
" Adequate resources (financial and human) will be required to modernize the Planning Act and to incorporate ecological-based planning.

Thank-you for your attention to this matter.

Letter to Steve Ashton

Minister of Conservation
Room 333, Legislative Building
450 Broadway Avenue
Winnipeg, Manitoba

Dear Mr. Ashton:

We would like to thank you for your time and the time of your departmental staff (Mr. Kagan and Mr. Beck) for providing us the opportunity to discuss the proposed changes to the Livestock Manure and Mortalities Management Regulation (MR 42/98).

We are writing today to capture some of the discussion that took place with respect to the regulatory review as well as to provide additional points of concern, which we may have omitted in our oral briefing.

Main areas of concern

" The barns are still not regulated under the Environment Act even though they emit airborne pollutants. This has implications for people's health for those who live in proximity to intensive livestock operations.
" Temporary storage of untreated manure in the pits underneath the barns is exempt from this regulation. As we indicated with our photo gallery, this poses a severe environmental hazard when barns are inundated with flood waters such as the event in southeastern Manitoba (June 2002) and the Great Flood of 1997 (Red River Valley). These cement storage pits also have the potential to crack and regulatory oversight must be provided to ensure their integrity.
" Barns constructed on the 100-year event flood plain are still grand-fathered and are allowed to operate without any remediation or decommissioning strategy. (Section 5)
" Animal Units (AU) are not calculated cumulatively across species nor is there any regulatory or policy instrument to deal with ecological carrying capacities of the soil, water or air. We also suggest that the AU threshold to trigger manure management and nutrient management planning be reduced to 250 AU's.
" Penalties for infractions are minimal and do not create a deterrent for following the law.
" While the proposed changes, moves us towards broader nutrient management planning, which we support, the only nutrient being considered is nitrate nitrogen. It is becoming well documented that in some areas of Manitoba, with an abundance of concentrated livestock operations, and that have liquid systems in existence for longer periods of time, phosphorus is being applied in excess amounts.
- There is no indication if nutrient management plans will be required in areas other than special nutrient management areas, which may potentially have other nutrients cumulating in excess quantities.(ie, phosphorus)
- There does not appear to be any indication that manure management plan registration forms will be modified to reflect nutrient management planning. We also recommend that manure management planning be scheduled in the regulation (with proper forms and records of information) and that plans be approved through a permitting process.
- Manure management plans should be made available to the public.
- There is no clause, which allows soil sampling to be conducted at the four-foot level.

" The phase in period (2008) for prohibiting winter spreading of untreated manure for operations in the 250 to 400 AU range is much too generous, however, given the impacts associated with winter spreading, we recommend that all application of untreated liquid manure in winter be prohibited.
" "Surface watercourse" definition under Section 1 implies that no set backs are required in private property and that possible recharge zones such as sloughs and improperly designed dugouts, intermittent streams and drainage ditches can be a conduit for groundwater contamination.
" We note that the regulation does not prescribe any set back distances to surface watercourses or wells, springs or sinkholes for the application of untreated manure to fields.
" We welcome the proposed water quality monitoring section of the regulation but require further clarification on its design. (Section 18) Specifically,
- We would like clarification on the protocol utilized in sampling and the type of forms or schedule that will be required? As it now stands, existing structures with groundwater monitoring wells are sampled by the operator.
- Will the protocol include baseline measurements? If not, they should.
- We would like to know whether non-permitted manure storage structures will be captured in the water monitoring program during their phased-in licensing period?
- We would like to know if this program will conform to all the recommendations accepted by your government in November of 2000 from the Drinking Water Advisory Committee Report, and specifically make results available to the public?

" We also suggest that the surface water quality-monitoring program in Manitoba be greatly expanded to reflect the expansion of the livestock industry.
" We welcome the proposed section for decommissioning, however this section appears to be vague in its application. We suggest that all manure storage structure operators over the 250 AU threshold be required to file a decommissioning plan and that environmental standards be set to rehabilitate the site of operation. (Section 19) We request that decommissioning plans be scheduled in the regulation and that plans be approved through a permitting process.
" In respect to decommissioning and possible environmental problems, we request that the government respect the recommendation from the "Finding Common Ground" report, and require operators to file an environmental performance bond for all manure storage structures.
" Any "variations" applied (Section 20) to this regulation must be made public knowledge and an appeal section should be included within this provision.
" We welcome the attempt to end grand-fathering of all manure storage structures in Manitoba to guarantee that all structures are permitted and operating to required standards, but stress that the phase-in period for compliance is too generous. (Section 22) We suggest that all non-permitted structures be compliant by the end of 2004.
" The review period of "no later than five years" must be reinstated as its intention still allows for amendments to be made when required. Possible modification to this clause could be allowing for minor revisions at any time and major review, no later than five years.
" Schedule A - Section 2 (g) should be reinstated so that protection to the underground water table can still be maintained.
" We recommend that inspection records and reports be made available to the public to increase public awareness of the performance of the industry.


General changes which we conditionally support

" We support the definition of contractor and subsequent assignment of liability through the chain of command. We are assuming that a contractor (and/or applicator) requires bonding.
" The ending of un-permitted manure storage structures is greatly welcomed, however, the time line for compliance needs to be shortened.
" The realization of "special nutrient management areas" is welcomed, however this classification requires broader definition, as it does not appear to consider cumulative nutrient build-up. We also suggest that linkages be made with MR 126/88 (Sensitive Areas Regulation) and that MR 126/88 be updated to reflect the rapid growth of the intensive livestock industry.
" The prohibition of burning livestock manure is welcomed, however, we suggest this prohibition be extended to mortalities.
" Removal of excess nitrogen applications to forage crops is welcomed, however we reiterate the need to move to regulating phosphorus. We stress that application of untreated manure in these areas must be stopped (or greatly reduced) until nutrient levels correspond with crop requirements.
" Certification requirements for contract land applicators are welcomed however, we recommend that non-contract applicators above the 250 AU threshold be required to obtain certification. We realize that this may place a burden on some of the family farm operations, which we support, however we suggest that financial resources be put in place for these family farm operations to obtain certification. The carrying capacity of the environment does not recognize the difference between a family farm operation and corporate/investor farm operation.
" As stated, the move towards nutrient management planning is welcomed.
" The minor changes to the mortality management section are welcomed. However, we recommend that mortality management plans required for operations above the 250 AU threshold be scheduled in the regulation and that mortality management plans be approved through a permitting process. We also suggest that the burial of mortalities be nearly as stringent as the requirements set out in schedule A of the regulation. We notice that the rendering industry in Manitoba currently has insufficient capacity to handle mortalities in the province and request your government's long term solution to this problem (other than burying dead animals all over the rural countryside).
" We welcome the "confined livestock area" section changes but suggest that the phase in period be shortened.
" As mentioned, we conditionally support the decommissioning and water quality monitoring sections proposed for the regulation.

Resource Issues

We realize that with the proposed amendments to the regulation, there will be added resources required to inspect, permit and monitor the industry. We strongly recommend that these resources be added to the department, at the cost to the industry and not be borne by the public. As an example, we estimate that if the irrigation industry in Manitoba was levied 10 cents per cubic metre of water usage, a total of $2.5 million per year can be accrued to the government. (Assuming the industry utilizes 25 million cubic metres a year). For the hog industry, a 10 cent levy, may be able to generate $0.5 million per year. (Assuming the industry utilizes 5 million cubic metres a year).

As we mentioned, and as you may be aware, the Manitoba Pork Council has set its budget to $3.4 million for the year 2003. Their income is based on a regulated per animal check-off. We strongly urge your government to amend this regulation and acquire 50% of the fund ($1.7 million) and utilize it in a beneficial fashion to improve our staffing levels in the department and to improve the quality of the environment.

As an alternative, your government can place a modest 25-cent environment levy on every pig born in this province. That would generate close to $2 million a year.

In our discussion with you, we suggested that fines should be greatly increased, to reflect the costs of enforcement and to set a deterrent to polluters. We noticed that administration fees are proposed for the filing of manure management plans. We suggest that these fees be increased and that they be developed on a scale corresponding to the size of operation. In this respect, we suggest that all fees for permits and environmental levies be adjusted based on size of operation and that penalty fees be applied for late filing. We also suggest that fees for permits and environmental levies be greatly reduced (or even removed) for those livestock operations that do not utilize a liquid based system.

And finally, we urge that the policy of 6% vacancy rate for the workforce in high priority areas within your government and in particular, the Conservation Department, be terminated. We suggest the enforcement capacity of the department match that of the growth of the industry.


General Conclusion

Hog Watch Manitoba supports alternative housing systems for pigs that meets their fundamental behavioral and social needs which includes these minimum components:

1) Group housing for breeding sows;
2) Straw-based housing for pigs.

It is our belief that if these types of housing system systems were used, many environmental, human health and animal welfare impacts would be greatly minimized. As well a switch to more animal-friendly systems would help address growing consumer concern over animal welfare and food safety.

We suggest that any new expansion of the hog industry utilize these straw-based systems.

We further suggest that liquid manure systems be phased out over the next decade and that in the interim (phase out period), all liquid manure operations immediately:

1) install ground water monitoring wells
2) treat the waste through an aerobic process to kill off any unwanted pathogens
3) phase out the use of hormones and sub-therapeutic antibiotics

Hog Watch Manitoba supports the family farm and believe that the true family farm is one which the family are engaged in the day to day labor and management of the farm and reside there as well.

We support the Nebraska definition of a "family farm corporation" where the majority of the voting stock is held by members of a family and that no corporation, other than family farm corporation or syndicate shall acquire or otherwise obtain an interest in land for the purposes of farming.

A necessary component of the goal of promoting family farms is the reinstatement of single desk selling which provides equity, economic bargaining power and transparency to the individual farmer.

Hog Watch believes in the protection of all workers in society including agricultural workers, and insists that they should be included within the employment standards code. We also believe that workers compensation should be mandatory for every worker in this sector.

We feel that there is an opportunity for family farmers to start marketing their hogs as "identity preserved" or "organically produced" as coming from more humane and environmentally regenerative systems. As consumers learn more about the "industrial style" hog barn, many are already expressing a desire to purchase pork products from alternative systems such as the Niman Ranch product in the U.S. and Freedom Food in Great Britain.

In closing, we reiterate the need to call for a moratorium on the expansion of new intensive livestock operations in Manitoba. This moratorium will give the province the time to catch up, take stock and implement regulatory change. As you may be aware, Quebec has issued an 18-month moratorium to bring change to their existing laws. As it stands and prior to the moratorium, Quebec's "regulation respecting the reduction of pollution from agricultural sources", is far superior to what Manitoba is currently proposing for MR 42/98.

Thank-you, for your consideration.

Turning hog manure into heat

Manitoba urged to investigate Saskatchewan system
Monday, November 17th, 2003
By Leah Janzen

ENVIRONMENTALISTS say Manitoba should investigate a new method that turns hog manure into a valuable source of power.

The system, developed by a Saskatchewan company, takes the smell and dangerous chemicals out of hog manure and can eventually turn the waste into heat and power for homes.

"These new approaches need to be tried or the industry will find itself very unwelcome in the province,'' said Fred Tait, a member of Hogwatch Manitoba. "Its future viability is at stake.''

There are about 1,668 commercial hog operations in the province producing about four million animals a year and adding about $900 million to the economy.

But nearly every time a new intensive livestock operation is proposed in Manitoba, opponents argue against it, citing noxious odours, dangerous runoff from manure spreading and water contamination.

Clear-Green Environmental Inc., a Saskatoon company, says it can deal with those concerns and then some.

The company is in the process of building a $1.5- million demonstration facility north of Saskatoon in collaboration with SaskPower to showcase the technology it says will make hog production safe and clean and will provide a new power source for hundreds of homes in the province.

The system takes manure directly from the hog barn to a large tank -- eliminating the need to dig manure lagoons for storage.

Once inside the tank, the manure is heated to encourage development of bacteria. The bacteria digests the organic matter in the manure, producing methane gas -- which is similar to natural gas.

That methane gas can be converted into heat and power.

Nitrogen, phosphorus and potassium -- chemicals in the manure which have been blamed for polluting lakes, rivers and wells -- are broken down, purified and sold as fertilizer.

All that's left after the process is complete, said Clear-Green Environmental president Ben Voss, is water. The technology shows so much promise that SaskPower has signed on as a partner.

Larry Christie, a SaskPower spokesman, said the utility has invested $500,000 for four micro-turbines for the project which will convert the gas into heat and energy.

Early estimates suggest the average farm -- with about 2,500 animals -- will produce enough gas to provide electricity to 100 homes.

Voss concedes the technology is expensive, but he said the system won't cost farmers any more.

He said Clear-Green will pay to construct and operate the plants. Farmers will pay a small amount to Clear-Green to convert their manure. Heat generated by the system will be provided to the farm to heat the barns.

Tait said he'd like to see the Manitoba government establish a similar project.

Manitoba Hydro spokesman Jim Peters said the utility has not been approached by Clear-Green officials, but would be interested in speaking to the company about the technology and its possible applications for Manitoba.

"All of these alternative energy sources are of interest to us,'' he said.

Methane Gas Capture
Methane Gas Capture and Technology

Methane as a Greenhouse Gas (GHG)

Methane is responsible for about 18% of the enhanced greenhouse effect'. According to the Intergovernmental Panel on Climate Change, methane concentrations now are at their highest levels in 420 000 years2. Although there is considerably less methane than carbon dioxide in the atmosphere, it is a serious problem. Methane is 21 times more effective at trapping heat than carbon dioxide.

GHG's and the Hog Industry

Manure in storage and on land is a significant source of methane emissions. When manure decomposes in the absence of oxygen (anaerobic), much of it is converted to methane gas. When oxygen is present (aerobic), decomposing manure releases nitrous oxide, another potent GHG.

Manitoba's livestock industry in growing. The sale of Manitoban hogs increased from 4.3 million to 5.3 million head from 1999 to 2000. A full-grown pig produces 4.5 kg or 10 Ibs of manure a day. Projects to reduce emissions from hog manure offer a considerable opportunity to start meeting GHG reduction commitments under the Kyoto Protocol.
At the "Greenhouse Gases and the Hog Industry" workshop (December 9, 2002), the Canadian Pork Council (CPC), along with participants from pork and farm associations; federal and provincial departments of agriculture, environment and natural resources; agrologist institutes; research centres and Chairs of pork-related congresses identified priorities in the development and application of GHG reduction technologies for the pork sector. They include 3:

" Projects should consider whole farm applications
" Projects should be applicable to small and large scale farming operations
" There is a need to focus on handling, storing, and covering manure
" Demonstrations for N use efficiency anaerobic digesters were recommended.

Anaerobic Digestion
Biogas recovery systems have been identified as one of the most promising areas of development for the significant reduction greenhouses gas emissions from agriculture. Biogas recovery systems are also known as anaerobic digesters.
During anaerobic digestion, microorganisms break down manure in an oxygen-free environment. One of the natural products of this process is biogas. Biogas typically consists of 60 to 70 percent methane, 30 to 40 percent carbon dioxide and trace

amounts of other gases4. Depending on digester design, methane content can reach as a high as 95%.
Benefits of Biocias Recovery
Captured biogas can be used to generate heat, hot water or electricity. As such, recovery systems significantly reduce energy costs for both private and commercial operations. As such, the use of biogas recovery systems fits with AAFC's Sustainable Development Strategy: "by 2006, there will be an increase in the ratio of agricultural output energy over input energy"5.
Biogas can also be flared to control odour if energy recovery is not feasible. Both flaring and energy production reduce greenhouse gas emissions.
Other benefits to biogas recovery include:
" Odour control - the effluent odour from anaerobic digesters is significantly less than odours from conventional manure management systems. Odour reductions of 98 percent have been achieved by pilot digester projectsb.
" Water quality protection - when digesters are properly managed, phosphorous and metals settle out. When processed manure is applied to the land, these elements are left behind, keeping them out of surface waters. Digesters are also made of concrete or steel, protecting water from pollution with pre-treated manure.
" Public health protection - heated digesters isolate and destroy disease-causing organisms that might otherwise contaminate surface waters and pose a public health risk.
" High quality endproducts - anaerobic digesters reduce ammonia losses. Digested manure can contain more valuable nitrogen for crop production.
System Desiqn
Biogas recovery systems have four basic components: a digester, a gas-handling system, a gas-use device and a manure storage tank or pond to hold the treated effluent prior to land application. Digesters can effectively process manure in 2-3 days or 25-30 days', depending on the technology used. There are three types of digesters:
" A complete mix digester is a heated tank of either reinforced steel or concrete, with a gas-tight cover. The contents are mixed periodically by a motor-driven impeller or a pump. This type works best with slurry manure (typical of hog operations) with total solids content between 3 and 10 percent.
" A covered lagoon digester is an earthen lagoon fitted with a cover that collects biogas as it is produced. They are best suited for manure collection systems with

very low solids content. Because they are not heated, they do not produce adequate biogas flow for energy production during colder months.
" A plug-flow digester is a long, narrow heated tank - often built below ground level - with a gas-tight cover. They are used only for dairy manure, and require thick manure ranging from 11 to 13 percent solids. As this design is not relevant to hog operations, it will not be discussed in subsequent sections.

Biogas Recovery System Costs
Cost depends on the size of the operation. The larger the operation, the lower the per unit cost of the biogas recovery system. The Environmental Protection Agency suggests a break-even herd size of 2500 hogs for a complete mix digester, and 1350 hogs for a covered lagoon digestera.
On a per unit basis, heated digesters cost approximately $200-420 CDN per hog and covered lagoon digesters cost $200 - 400 CDN per hog'. Biogas recovery systems have a payback period of 3 to 7 years when biogas products are used for energy production.

There are currently three Canadian companies that design/build biogas recovery systems, provide technology, and offer consulting services:

Biogas Recovery - A Scalable Technology
Biogas recovery technologies have applications beyond the barn. In Kristianstad, Sweden, biogas plants are used to co-digest municipal solid waste with manure and other organic biomass for the production of energy and fertilizer. The project offers a feasible and sustainable solution to waste problems in many countries.
Program highlights10:

" Built on the site of a closed-down sugar beet factory, tanks from the former sugar wastewater treatment plant are re-used as digestion and storage tanks. Kristianstaders separate their organic waste into paper bags, which are collected by municipal services. In 1998, 3100 tonnes of household waste was collected and digested from 100 000 households.
" Industrial waste is also processed at a cost of approximately $65/tonne (CDN). A total of 41 200 tonnes of manure (hog, cattle and poultry), 24 600 tonnes of abattoir waste and 900 tonnes of distillery waste was processed by the municipal digester in 1998.
" Gross biogas recovery for 1998 was 20 000 MWh. 2 100 MWh were used to heat the digester. 17 900 MWh were sold to the district heating plant.

This type of technology may be appropriate for small municipalities whose landfills are not large enough support a methane recovery operation. It also reduces the amount of waste that enters landfills.
