1. Brief Synopsis of the Subject, Substance and Issues

The Department of Natural Resources and Environmental Control, The Department of Agriculture and the Delaware Nutrient management Commission are proposing general permit regulations for concentrated animal feeding operations (CAFOs). The proposed CAFO regulations will amend section 9 (The General Permit Program) of the Regulations Governing the Control of Water Pollution. The Clean Water Act and recent revisions to federal regulations define a CAFO. The draft regulations were developed cooperatively with the involvement of the Department of Agriculture, Delaware Nutrient Management Commission, Department of Natural Resources and Environmental Control, Natural Resource Conservation Service and the University of Delaware.

2. Possible Terms of the Agency Action:

N/A

3. List of Other Regulations That May be Impacted or Affected by the Proposal:

Regulations Governing the Control of Water Pollution (Amended May 14, 2003)

4. Notice Of Public Comment

The Department of Natural Resources and Environmental Control, the Department of Agriculture and the Delaware Nutrient Management Commission will hold public hearings on January 25, 2005 at 6 PM at the Farmington Fire Hall and January 27, 2005 at 6 PM at the Gumboro Fire Hall to receive comments on proposed amendments to the Regulations Governing the Control of Water Pollution. Comments should be sent in writing to Peder Hansen, Surface Water Discharges Section, Division of Water Resources, DNREC, 89 Kings Hwy., Dover, DE 19901.

9.0 The General Permit Program

Introduction. This section of the regulations, the General Permit Program, is designed to provide NPDES permit coverage to a specified group, category or class of discharges that are substantially similar in nature or type of pollutants discharged. These regulations outline the general provisions or requirements that apply to all discharges within the specified category. This approach eases the administrative burden of developing and issuing a large number of individual NPDES permits for essentially the same type of discharge. By issuing general permits, the Department can provide a quicker and less expensive mechanism for the regulated community to obtain permit coverage. It also allows staff resources to concentrate on discharges that may have more significant potential for impacting the quality of Delaware's surface waters.

General NPDES Permits as defined by federal regulations in 40 C.F.R. §122.28, authorize a category of discharges from sources within a defined area that share certain similarities. General NPDES Permits are self-implementing standards applicable to multiple dischargers that the DNREC has determined can best be regulated as a class. Conversely, individual NPDES permits are issued to a potential discharger who applies for a permit with special conditions specifically tailored to the discharger. Thus, a General NPDES Permit is an agency statement of general applicability and future effect that implements and prescribes law and as such is a regulation.

Although no individual permits will be issued to the categories of dischargers covered by this section of the regulations, the subsections dealing with each category may be referred to as "General NPDES Permits" and the entire Section of these regulations may be referred to as the "General NPDES Permit Program."

In order to obtain coverage under this section of these regulations (the General NPDES Permit Program), most persons will be required to file with the Department a Notice of Intent to be covered in accordance with 40 C.F.R. §122.28(b)(2). The Department will consider this the equivalent of an NPDES Permit application for a General NPDES Permit.

Subsection 9.1 provides NPDES permit coverage for storm water discharges associated with industrial activity. Industrial activity is that which is directly related to manufacturing, processing, raw material handling or waste handling. The regulations in Subsection 1 seek to define a program for controlling material handling and other industrial activities such that the potential for exposing significant materials to precipitation and the subsequent transport of such materials via storm water runoff or infiltration is eliminated or minimized to the maximum extent practicable. Significant materials are those substances, products or wastes that become exposed to precipitation as a result of the industrial activity and potentially contribute pollutants to storm water runoff or storm water infiltration. The types of activities or categories of industries covered under this subsection are listed in §9.1.1.1, as well as in the federal regulations, 40 CFR Part 122.26(b)(14).

Part 1 of Subsection 9.1 consists of general provisions that apply to each category of industrial activity specified in §9.1.1.1. Part 2 outlines specific provisions applicable to storm water discharges associated with land disturbing activities (i.e. construction activities). The regulations in Part 2 are designed to mesh NPDES permit program requirements with existing provisions for sediment and erosion control under 7 Del.C. Ch. 40 and the Delaware Sediment and Stormwater Regulations. The remaining Parts under Subsection 1 outline category-specific storm water requirements that are tailored to the activity conducted.

Subsections 9.2 through 9.6 provide NPDES permit coverage for the following categories of discharges: discharges from aquaculture or aquatic animal production facilities; discharges from the clean up of gasoline and fuel oil released from underground storage tanks; discharges from feedlot or concentrated animal feeding operations; discharges associated with car washes and other motor vehicle washing operations; and discharges associated with the operation of swimming pools and spas.

9.4 The Concentrated Animal Feeding Operation (CAFO)

PREAMBLE

These regulations have been developed pursuant to 3 Del.C. §2201-2290 and 7 Del.C. §6000 et.al., 40 Code of Federal Regulations (C.F.R) §122.23 and 40 C.F.R. §122, Appendix B and 40 CFR part 412. 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 regulations will function as the baseline CAFO standards for compliance of NPDES permits applicable to certain farms. The Delaware Department of Agriculture (DDA) will administer these regulations, while the legal framework and authority is maintained by the Delaware Department of Natural Resources and Environmental Control. In general, NPDES general permits, as provided in these regulations, are effective for five years. After five years, new or updated CAFO General Permit regulations will be promulgated. These regulations were developed by the Delaware Nutrient Management Commission, the Delaware Department of Agriculture and the Delaware Department of Natural Resources and Environmental Control. They are to be adopted with the guidance, advice and consent of the Commission.

9.4.1 Authority.

These regulations are promulgated pursuant to the authority provided by 3 Del.C. §2200 et.al. and 7 Del.C. §6000 et.al.

9.4.2 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 sustain and provide a profitable agricultural industry and to help meet or exceed Federal mandated water quality standards.

9.4.3 Definitions.

For purposes of these regulations, the following words or terms shall have the meanings as indicated:

“Animal Feeding Operation” or “AFO” means a lot or facility (other than an aquatic animal production facility) where the animals 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 the animal confinement areas do not sustain crops, vegetation, forage growth or post-harvest residues in the normal growing season. 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 by a certified nutrient management consultant 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 on cropland and pastureland: animal wastes, manures, composted dead animals, or process wastewater from any animal feeding operation.

“Applicant” means any person seeking and or required to obtain an individual CAFO permit or coverage under a general permit.

“Apply,” “applying,” or any variation of the word “apply,” as it relates to the application of nutrients, means the human controlled mechanical conveyance of nutrients to land for the purpose of applying organic and/or inorganic nutrients.

“Best Management Practices” or “BMP” means those practices that have been approved by the Delaware Nutrient Management Commission.

“Catastrophic Mortalities” means any mortality that exceeds the approved disposal system capacity 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.

“Concentrated Animal Feeding Operation” or CAFO” is an animal feeding operation that is subject to the terms and conditions of these regulations. A CAFO is designated by the confinement of the number of animals specified in section D of these regulations.

“Delaware Nutrient Management Commission,” “DNMC,” or “Commission” means the Commission established by 3 Del.C. §2220 “or its designee.”

“Department” means the Delaware Department of Agriculture.

“Discharge of a Pollutant” means the addition of any pollutant or combination of pollutants, to state waters or contiguous zones, or the ocean, from any source or activity other than a vessel or other floating craft when being used as a means of transportation and in compliance with Section 312 of the Act. This definition includes additions of pollutants into State waters from:

Surface runoff that is collected or channeled by man;

Discharges through pipes, sewers, and other conveyances which do not lead to a treatment works; and

Discharges through pipes, sewers, or other conveyances, leading into a treatment works other than a publicly owned treatment works (POTW).

“Drainage Ditch” is defined as a constructed or reconstructed watercourse with a drainage area less than 800 acres. A constructed or reconstructed watercourse with a drainage area greater than 800 acres is considered a stream.

“Effluent Limitation” means any restrictions, prohibitions, or permit requirements established under State or Federal law, including but not limited to, standards of performance for new sources, best management practices or BMPs, effluent standards and ocean discharge criteria on the quantities, rates, and concentrations of the chemical, physical, biological, or other constituents discharged into State waters.

“Freeboard Action Level” is the liquid level within a lagoon or other liquid storage structure that indicates the structure is full and implies that immediate steps be taken to transfer liquid out of the waste storage structure.

“General Permit” means an authorization granted to a category of point sources discharges pursuant to Section 9 of the Regulations Governing the Control of Water Pollution.

“Ground Water” means any water naturally found under the surface of the earth.

“Inorganic Fertilizer(s)” means a fertilizer comprised of chemically synthesized plant nutrient elements that are essential for plant growth and include at least nitrogen or phosphorus.

“Liquid Manure” means usually less than 8.0% solids. Wash water, runoff, precipitation, and so forth are added, if needed to dilute the manure and lower the solids content.

“Liquid Manure Handling System” means an operation where animals are raised outside with swimming areas or ponds, or with a stream running through an open lot, or in confinement buildings where water is used to flush the manure to a lagoon, pond, or some other liquid storage structure.

“Manure” is defined to include fecal and urinary defecations of livestock and poultry; may include spilled feed, bedding, soil, compost and raw materials if commingled with manure.

“NPDES” (National Pollutant Discharge Elimination System) means the national program for issuing, modifying, revoking and reissuing, terminating, monitoring and enforcing permits for the discharge of any pollutant or combination of pollutants and imposing and enforcing pretreatment and sludge requirements pursuant to Sections 307, 402, 318, and 405 of the Act.

“Notice of Intent (NOI)” means the form used to serve as a notification of the intention of the facility identified on the form to adhere to the provisions of The Concentrated Animal Feeding Operation Regulations.

“Nutrients” means nitrogen, nitrate, phosphorus, organic matter and any other elements necessary for or helpful to plant growth.

“Phosphorus Site Index or PSI” means the assessment tool developed by the University of Delaware designed to evaluate the site characteristics and management factors in determining Phosphorus loss to the environment.

“Person” means any individual, partnership, association, fiduciary, corporation, or any organized group of persons, whether incorporated or not.

“Pollutant” means any substance, which causes or contributes to, or may cause or contribute to, pollution.

“Process Wastewater” means any process-generated wastewater directly or indirectly used in the operation of an AFO (such as spillage or overflow from animal or poultry watering systems; washing, cleaning, or flushing pens, barns, manure pits; direct contact swimming, washing, or spray cooling of animals; and dust control) or any precipitation (rain or snow) which comes into contact with any manure or litter, bedding, or any other raw material or intermediate or final material or product used in or resulting from the production of animals or poultry or direct products (e.g., milk, eggs).

“Production Area” means that part of an AFO that includes the animal confinement area, the manure storage area, the raw materials storage area and the waste containment areas, also includes egg washing or processing facility and any area used in the storage, handling, treatment or disposal of mortalities.

“Realistic Yield Goals” are defined as the expected crop yields based on the best 4 out of 7 years of recorded data. Without yield records, one shall use soil productivity classes. Yield goals higher than the average, require written justification from a certified consultant.

“Secretary” means the Secretary of the Delaware Department of Agriculture or his/her designee.

“Sinkhole” is defined as a depression in the landscape where limestone has been dissolved.

“Soil Productivity” means the capacity of a soil, in its normal environment, to produce a specified plant or sequence of plants under a specified system of management. The “specified” limitations are needed because no soil can produce all crops with equal success and a single system of management cannot achieve the same effect on all soils. Productivity means the capacity of soil to produce crops and is expressed in terms of yields.

“State Nutrient Management Program” or “SNMP” means all the nutrient management program elements developed by the Commission, whether or not reduced to rules or regulations.

“State Waters” or “Waters of the State” means all water, on the surface and under the ground, wholly or partially within, or bordering the State, or within its jurisdiction including but not limited to:

• All other waters of the State, such as lakes, rivers, streams (including intermittent and ephemeral streams), drainage ditches, tax ditches, creeks, mudflats, sand flats, wetlands, sloughs, or natural or impounded ponds;

• All impoundments of waters otherwise defined as waters of the State under this definition;

• Wetlands adjacent to waters (other than waters that are themselves wetlands) identified in the above four statements.

• Waste and storm water treatment systems or waste storage structures including, but not limited to, treatment ponds or lagoons designed to meet the requirements of the Act (other than cooling ponds which otherwise meet the requirements of this definition) are not “State waters” or “waters of the State.” This exclusion applies only to manmade bodies of water, which neither were originally created in waters of the State nor resulted from the impoundment of waters of the State

“Vegetated Buffer” means a narrow, permanent strip of dense perennial vegetation established parallel to the contours of and perpendicular to the dominant slope of the field for the purposes of slowing water runoff, enhancing water infiltration, and minimizing the risk of any potential nutrients or pollutants from leaving the field and reaching surface waters.

“Water Quality Standard” means any rule or limit established by the Secretary of the Department of Natural Resources and Environmental Control which consists of a designated use or uses for waters of the State and the water quality criteria for such waters based upon such designated uses.

“25-Year, 24-Hour Rainfall Event” means the maximum 24-hour precipitation event with a probable recurrence interval of once in 25 years, as defined by the National Weather Service Technical Paper Number 40, “Rainfall Frequency Atlas of the United States”, equivalent to regional or state rainfall probability information developed there from, or a rain event greater than 5.7 inches for New Castle county, 5.9 for Kent county and 6.3 for Sussex county.

“100-Year, 24-Hour Rainfall Event” means the maximum 24-hour precipitation event with a probable recurrence interval of once in 100 years, as defined by the National Weather Service Technical Paper Number 40, “Rainfall Frequency Atlas of the United States”, equivalent to regional or state rainfall probability information developed there from, or a rain event greater than 7.3 inches for New Castle county, 7.6 for Kent county and 7.9 for Sussex county.

9.4.4 Applicability

*Note: An alternative criterion for square footage calculations may be utilized and adopted as policy that qualifies a CAFO based on the area within the confined facility. For example the animal density of 0.75 square feet per bird calculates to 93,750 square feet and can be defined as a CAFO. This alternative may not supersede the actual number of chickens maintained.

9.4.4.2.2 Provided one of the following conditions are met and the number of animals is in the range specified below, the operator has a duty to apply:

9.4.4.2.2.1 Pollutants are discharged into waters of the State through a man-made ditch, flushing system, or other similar man-made device; or

9.4.4.2.2.2 Pollutants are discharged directly into waters of the State, which originate outside of and pass over, across, or through the facility or otherwise come into direct contact with the animals confined in the operation.
