7201 Regulations Governing the Control of Water Pollution, 9.5 The Concentrated Animal Feeding Operation (CAFO)
 
1. Title of the Regulations:
Section 9.5: Concentrated Animal Feeding Operations of 7201 Regulations Governing the Control of Water Pollution (Title 7, Delaware Administrative Code 7200, §9.5)
 
2. Brief Synopsis of the Subject, Substance and Issues:
These proposed regulations have been developed pursuant to 3 Del.C. §2201-2290 and 7 Del.C. §6000 et.al. and under DNREC's delegated authority. These statutory and regulatory authorities establish the requirement that a National Pollutant Discharge Elimination System (NPDES) permitting program for Concentrated Animal Feeding Operations (CAFOs) be implemented. These proposed regulations amend the current regulations and will function as the baseline CAFO standards for compliance of NPDES CAFO permits applicable to certain farms. The Delaware Department of Natural Resources and Environmental Control (DNREC) will administer these regulations with the assistance of the Delaware Department of Agriculture (DDA). In general, NPDES CAFO permits, as provided in these regulations, are effective for five years. These regulations were developed by the Delaware Department of Agriculture and the Delaware Department of Natural Resources and Environmental Control.
 
3. Possible Terms of the Agency Action:
The revised regulation will clarify the current application, approval and reporting requirements for CAFO NPDES permits. Failure to promulgate revised regulations compliant with requirements of the Clean Water Act may result in forfeiture of the State NPDES program and subject Delaware farmers to federal enforcement action and third party lawsuits.
 
4. Statutory Basis or Legal Authority to Act:
7 Del.C. §6000 et. al.; 3 Del.C. §2200 et. al, and 40 CFR 122 and 412.
 
5. Other Regulations that may be Affected by the Proposal:
Delaware Nutrient Management Regulations 3 Del.C. §2200
 
6. Notice of Public Comment:
The proposed regulations are posted on the Delaware Department of Agriculture website (www.dda.delaware.gov) and the DNREC website at www.dnrec.delaware.gov.

Regulatory Flexibility Act Analysis:
“Regulations for Concentrated Animal Feeding Operations (CAFO)”
July 2011
 
Regulatory Action:
The Delaware Department of Natural Resources and Environmental control, and the Delaware Department of Agriculture are proposing to adopt amended regulations, which will amend requirements to reduce point source pollution from farms where poultry, swine, beef cattle, dairy cattle and horses are raised also known as Animal Feeding Operation (AFO). Such farms can be substantial contributors to the pollution of the State’s waterways if manure and other waste products are not properly managed. The actions proposed by the Departments are necessary to achieve Delaware’s water quality goals and to comply with US Environmental Protection Agency directives.
 
Background on the Proposed Regulation:
Part 122, Sub Section 122 and 412 of the Clean Water Act require States to develop regulations governing the discharge of nutrients from farms into nearby waterways. Farms (AFOs) identified to have such discharges are required to obtain a National Pollutant Discharge System (NPDES) permit, more specifically and Concentrated Animal Feeding Operation (CAFO) permit. Under these proposed regulations the Delaware Department of Natural Resources and Environmental Control (DNREC) will administer such permits with the assistance of the Delaware Department of Agriculture. The proposed state regulations are required in order to keep our “at least equal to” status with USEPA. Failure to do so may result in federal enforcement actions against Delaware agricultural producers and withdraw of the Delaware’s delegated authority to administer the NPDES program.
 
Regulatory Flexibility Act Considerations
 
1. Nature and cost of reporting.
In order to assess and track implementation efforts to reduce the loads of nutrients reaching the waters of the State and to ensure compliance with these Regulations, the Commission is requiring farmers to file an annual report. These reports detail nutrient application rates to crop land during the preceding crop year as well as crop yields (which indicate nutrient removal). The 1999 Delaware Nutrient Management Law already requires such annual reports. The new regulations do have additional record keeping requirements, but the state agencies have obligated to provide technical assistance to help meet those additional requirements. Therefore there will be minimal cost to farmers from this requirement.
 
2. The nature and cost of required measures or investment.
In order to protect and improve water quality, these Regulations may require farmers to implement various best management practices (BMP) to prevent nutrient laden storm-water from leaving their farms. Such BMPs can include riparian buffers, storm-water control structures, grassed waterways, covered manure storage structures and mortality composters. There are approximately 1,400 farm operations in the state with livestock and/or poultry. Of that total, we predict approximately 370 will be subject to the proposed NPDES CAFO regulations. There is extensive cost share funding for such BMPs from both State and Federal sources. NRCS provided cost share funds of $7 million in 2009 and $8 million in 2010 to assist farmers with BMP implementation. Due to increased emphasis on the watershed, the federal government plans to provide additional funding to help all agricultural producers in the Chesapeake Bay watershed to implement additional BMPs designed to help achieve more stringent water quality standards. Farmers will also need to practice good house-keeping and manure handling on their farms. Technical assistance to achieve this is already available from the Department of Agriculture, The University of Delaware Cooperative Extension and NRCS. In addition, the state provides manure relocation assistance funding to help redistribute nutrients from areas which may have an overabundance of nutrients to areas with nutrient deficiencies. Utilizing federal, state, and private funding, $849,870 was spent on relocation in 2009.
 
3. The nature and cost of legal, consulting and accounting services.
There are no requirements in the proposed Regulations that would necessitate a need for legal and/or accounting services, however, in order to improve water quality, these Regulations may result in farmers needing to secure consulting services. Such technical assistance can be obtained from NRCS, The Delaware Department of Agriculture, and the University of Delaware Cooperative Extension at no cost to the farmer. The Commission/State provides cost share funds for the writing of nutrient management plans (NMPs). In 2010, over $450,000 of state funds were provided to producers to offset the cost of drafting NMPs.
 
4. The ability of the entity to absorb or recover the added costs without suffering economic harm and without adversely affecting competition in the marketplace.
These Regulations are based on solid environmental science, but also take into consideration and accommodate a variety of factors, including the ability of farmers to absorb or recover any added costs without suffering economic harm and without adversely affecting competition in the marketplace. As indicated above there is extensive cost share assistance from both State and Federal sources to implement any BMPs that might be required to contain a farm’s nutrient laden storm-water. Additionally technical guidance is available at no cost from a variety of sources. It is also important to note that the proposed regulations are required by EPA and similar regulations are being or have been implemented nation-wide. If Delaware does not adopt and implement said regulations, then EPA will implement and enforce similar federally based regulations in Delaware.
 
5. The added cost to the Department if exemptions or lesser requirements were promulgated.
The actions proposed in these Regulations are necessary to achieve water quality goals therefore any lessening would adversely affect the health and well being of people, animals, and plants living within the State. Failure to implement these regulations could lead to enforcement action by EPA against both the State and Delaware Farmers. This could include fines and the withholding of grants and other funding. There are currently 372 CAFO permit holders in Delaware, which may submit new applications as a result of the expiration of their current permits and promulgation of the new proposed regulations. Due to funding and recent staff turnover, the staff capacity to administer and enforce 372 permits may present a challenge to the programs and Department of Agriculture and Department of Natural resources and Environmental Control.
 
6. The impact on the public interest of exempting or setting lesser requirements of compliance.
The actions proposed in these Regulations are necessary to achieve water quality goals, which will benefit the health and well being of people, animals, and plants living within the State. If the exemptions and lesser requirements are allowed, there will be less assurance that water quality standards will be achieved, which may result in increased occurrences of excessive macro algae growth (sea lettuce and other species), phytoplankton blooms (some potentially toxic), large daily swings in dissolved oxygen levels, loss of submerged aquatic vegetation, reduced populations of fish, shellfish, and other aquatic life, and fish kills. These symptoms of environmental degradation and habitat loss threaten the future of the Waters of the State and their significant natural, ecological, and recreational resources, which may result in adverse impacts to the local and State economies leading to reduced tourism, a decline in property values, lost revenues and a diminished quality of life, as well as violations of federal law.
 
7. What accommodations, if any, have been made in the regulations to address individual or small business concerns identified above?
These Regulations contain reasonable reporting requirements to ensure monitoring and compliance, but do not impose an undue regulatory or financial burden on farmers. In most situations reporting requirements are already required under the 1999 Delaware Nutrient Management Law. In addition, the NM Commission with the help of state and federal agency staff, and University of Delaware staff will provide written guidance through State Technical Standards to assist the regulated community with compliance.
 
As stated previously, these proposed Regulations may require additional measures and investments in order to protect and improve water quality; however, there is extensive federal and state cost share assistance available to meet the terms of these Regulations. In addition, the proposed Regulations do not create a need for legal and/or accounting services, while they may result in farmers securing consulting services, there is cost share available to cover such costs, which has been outlined previously in this document.
 
7201 Regulations Governing the Control of Water Pollution
 
9.5 The Concentrated Animal Feeding Operation (CAFO)
9.5.1 Authority, Purpose and Scope
9.5.1.1 Authority. These regulations are promulgated pursuant to the authority provided by 3 Del.C. §2200 et.al. and 7 Del.C. §6000 et.al, and 40 CFR 122 and 412.
9.5.1.2 Purpose. The purpose of these regulations is to establish requirements for certain animal feeding operations defined as a Concentrated Animal Feeding Operation (CAFO) in order to protect water quality from activities associated with CAFO management, to sustain and provide a profitable agricultural industry and to help meet or exceed federally mandated water quality standards.
9.5.1.3 Scope. CAFOs, as defined in §9.5.2.0 or as designated in §9.5.3.2 of these regulations are point sources subject to NPDES CAFO permitting requirements. Once an animal feeding operation (AFO) is defined as a CAFO for one type of animal, the NPDES requirements for CAFOs apply to all animals as referenced in these regulations that are held in confinement at the operation and all manure, litter and process wastewater generated by those animals or the production of those animals.
9.5.2 Definitions
9.5.2.1 For purposes of these regulations, the following words or terms shall have the meanings as indicated:
Adequate Storagefor liquid and solid manure systems, means the provision of at least four months holding capacity of liquid or solid manure in accordance with State Technical Standards.
Agricultural Storm Water Exemption means a precipitation related exempt discharge of manure, litter or process wastewater. The discharge is exempt provided the manure, litter or process wastewater has been applied in accordance with site-specific nutrient management practices that ensure appropriate agricultural utilization of the nutrients in the manure or process wastewater, which minimize nitrogen and phosphorus movement to surface waters. The agricultural storm water exemption does not apply to discharges from the production area.
Animal Feeding Operation or AFO means a facility (other than an aquatic animal production facility) where the following conditions are met: (1) Animals (other than aquatic) as referenced in §9.5.3.1.1 and §9.5.3.1.2 of these regulations that have been, or will be stabled or confined and fed or maintained for a total of 45 days or more in any 12-month period; and (2) the animal confinement areas do not sustain crops, vegetation, forage growth or post-harvest residues in the normal growing season. (3) Two or more AFOs under common ownership are considered to be a single AFO for the purposes of determining the number of animals in an operation, if the production areas adjoin each other or if the AFOs use a common area or system for the disposal of wastes. (For example, facilities or production areas that are commonly managed, co-located and share manure storage systems are considered a single AFO. A poultry operation with many facilities in a single location or address is deemed a single AFO).
Animal Waste Management Plan means a plan written in accordance with State Technical Standards that documents and recommends a combination of conservation practices and management measures for the handling, storage, treatment and management of any or all of the following for use in connection with animal wastes, manures, composted dead animals, or process wastewater from any animal feeding operation.
Applicant means any person seeking and or required to obtain a CAFO NPDES permit.

Application Area means land under the control of an AFO owner or operator, whether it is owned, licensed, or leased to which manure, litter or process wastewater from the production area is or may be applied.
Best Available Technology Economically Achievable (BAT)means those factors involved in assessing the implementation of the best available technology including cost to achieve required effluent reductions, the age of equipment or technology being implemented, process involved, process changes, engineering aspects of the application of various types of control techniques, non-water quality environmental impact, and other such factors as deemed appropriate by the Secretary and in accordance with State Technical Standards.
Best Conventional Pollutant Control Technology (BCT) means those factors related to the assessment of best conventional pollutant control technology including consideration of the reasonableness of the relationship between costs of attaining a reduction in effluents and the effluent reduction benefits derived, and the comparison of the cost and level of reduction of such pollutants from the discharges, process employed, process changes, engineering aspects of the application of various types of control techniques, non-water quality environmental impact and other such factors as deemed appropriated by the Secretary and in accordance with State Technical Standards.
Best Management Practices or BMP means those practices that have been approved by the Delaware Nutrient Management Commission and meet State Technical Standards. Best Management Practices (BMPs) are recommended activities which enhance agronomic results, benefit the environment, and prevent or reduce pollution to Waters of the State. BMPs are not to be interpreted as mandatory implementation actions of a plan (e.g., Pre-side dress Soil Nitrate Test, cover crops, vegetative buffer strips, litter additives, manure incorporation, timing/method, etc.) unless specified in the nutrient management plan, animal waste management plan, or site-specific practices described in §9.5.5.
Best Practicable Control Technology Currently Available (BPT)means those factors relating to the total cost of application of technology in relation to the effluent reduction benefits to be achieved from such application, age of equipment and facilities, processes, process changes, engineering aspects of the application of various types of control techniques, non-water quality environmental impacts, and other such factors deemed appropriate by the Secretary and in accordance with State Technical Standards.
Catastrophic Mortalities means any mortality that exceeds the designed disposal system capacity, as described in State Technical Standards, to accommodate losses within 24 hours. Most disposal systems are designed to handle the normal anticipated mortality. If enough animals are lost and the disposal system cannot hold them all without causing serious disruption in the disposal process, then it is a catastrophic loss.
Certified Nutrient Consultant means a person who is approved by the Delaware Nutrient Management Commission to engage in the activities of advising or consulting with another person who is required to have a certificate under the Delaware Nutrient Management Regulations, regarding the formulation, application, or scheduling of organic or inorganic nutrients within Delaware. Provided however any employee of any federal, State or local government agency or the University of Delaware, or other organization duly recognized by the Commission for such purpose, who provides advice or consultation in his capacity as such an employee, without compensation, shall not be deemed to be a nutrient consultant unless such advice and consultation constitutes a direct and substantial part of a nutrient management plan developed pursuant to these regulations.
Concentrated Animal Feeding Operation orCAFO means an animal feeding operation (AFO) subject to the terms and conditions of these regulations and defined as a “Large CAFO”, or a “Medium CAFO”, or “Designated” as a CAFO in accordance with §9.5.3.2 of these regulations.

9.5.7 Criteria for Siting New CAFO Facilities.
9.5.7.1 New CAFOs not permitted prior to the effective date of these regulations shall meet the following criteria:
9.5.7.1.1 New Source Siting Determination
9.5.7.1.1.1 Scope
9.5.7.1.1.1.1 Except as otherwise provided in an applicable “New Source Performance State Technical Standard”, a source is a “new source” if meets the definition of a new source as provide in these regulations; and
9.5.7.1.1.1.2 It is constructed at the site at which no other source is located;
9.5.7.1.1.1.3 It totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or
9.5.7.1.1.1.4 Its processes are substantially independent of an existing source at the same site. In determining whether these processes are substantially independent; the Secretary shall consider such factors as the extent to which the new facility is integrated with the existing CAFO; and the extent to which the new facility is engaged in the same general type of activity as the existing source.
9.5.7.1.1.1.4.1 In the event that an unforeseen circumstance, such as a natural or man-made disaster, has partially or completely destroyed a NPDES CAFO permitted facility or structure, the owner or operator of that NPDES CAFO permitted operation may request in writing a determination by the Secretary that replacement of that partially or completely destroyed facility or structure is not a “new source”. The Secretary may approve such determinations on a case by case basis considering the unique facts of each request and event. In addition, such determination must be requested and approved in writing before construction commences.
9.5.7.1.1.2 A source meeting the requirements to determine a new source as listed above in this section is a new source only if a new source performance standard has been approved in the State Technical Standards. If there is no such standard, the source is a new discharger.
9.5.7.1.1.3 Construction at a site at which an existing source is located results in a modification to the NPDES CAFO permit rather than a new source or a new discharger if the construction does not create a new building except where the Secretary has made an alternate determination as described in §9.5.7.1.1.1.4.1 of these regulations, structure, facility, or installation meeting the criteria of this section but otherwise alters, replaces, or adds to existing process or production equipment.
9.5.7.1.1.4 Construction of a new source has commenced if the owner or operator has:
9.5.7.1.1.4.1 Begun, or caused to begin as part of a continuous onsite construction program,
9.5.7.1.1.4.2 Any placement, assembly, or installation of facilities or equipment; or
9.5.7.1.1.4.3 Significant site preparation work including clearing, excavation, or removal of existing building, structures or existing facilities which is necessary for the placement, assembly or installation of new source facilities or equipment; or
9.5.7.1.1.4.4 Entered into a binding contractual obligation for the purchase of facilities or equipment which is intended to be used in its operation within a reasonable time. Options to purchase or contracts which can be terminated or modified without substantial loss and contracts for feasibility engineering, and design studies do not constitute a contractual obligation under the paragraph.
9.5.7.2 Siting of New Control Facilities.
9.5.7.2.1 Waste storage structures shall not be located in the 100-year flood plain unless the CAFO is designed and constructed such that the manure from a CAFO is protected from floodwaters from a storm of 24 hours duration having a one (1) percent chance of recurrence within a given year. Such events are defined as 100-year, 24-hour rainfall event. Waste storage structures and treatment lagoons are to be designed in accordance with State Technical Standards.
9.5.7.2.2 Waste storage structures shall not be located closer than 300 feet from any public water well nor 200 feet from a domestic water well.
9.5.7.2.3 No Waters of the State shall come into direct contact with the animals confined at the CAFO. Fences or other practices may be used to restrict such access in accordance with State Technical Standards.
9.5.7.2.4 Animal confinement areas shall not be located:
9.5.7.2.4.1 In the 100 year flood plain unless the animal confinement areas are protected from inundation and damage that may occur during that flood event.
9.5.7.2.4.2 Closer than 300 feet from any public water well, nor 200 feet from a domestic water well.
9.5.7.2.5 The handling, treatment, and management of CAFO wastes shall not:
9.5.7.2.5.1 Result in the inadvertent destruction or adverse modification of habitat that supports federally endangered or threatened species.
9.5.7.2.5.2 Create a public health hazard.
9.5.7.2.5.3 Result in groundwater contamination.
