GENERAL PERMIT FOR POLLUTANT MANAGEMENT ACTIVITIES FOR ANIMAL FEEDING OPERATIONS AND ANIMAL WASTE MANAGEMENT

AUTHORIZATION TO MANAGE POLLUTANTS UNDER THE VIRGINIA POLLUTION ABATEMENT PROGRAM AND THE VIRGINIA STATE WATER CONTROL LAW

In compliance with the provisions of the State Water Control Law and State Water Control Board regulations adopted pursuant thereto, owners of animal feeding operations having 300 or more animal units utilizing a liquid manure collection and storage system and animal waste end-users are authorized to manage pollutants within the boundaries of the Commonwealth of Virginia, except where board regulations prohibit such activities.

The authorized pollutant management activities shall be in accordance with the registration statement, supporting documents submitted to the Department of Environmental Quality, this cover page, Part I-Pollutant Management and Monitoring Requirements for Animal Feeding Operations, Part II-Conditions Applicable to this General Permit, and Part III-Pollutant Management and Monitoring Requirements for Animal Waste End-Users, as set forth in this section.

Part I

Pollutant Management and Monitoring Requirements for Animal Feeding Operations

A. Pollutant management and monitoring requirements.

1. During the period beginning with this general permit's effective date and lasting until this general permit's expiration date, the permittee is authorized to manage pollutants at the location identified in the registration statement and the approved nutrient management plan written for the animal feeding operation.

2. At earthen liquid waste storage facilities constructed after December 1, 1998, to an elevation below the seasonal high water table or within one foot thereof, groundwater monitoring wells shall be installed. A minimum of one up gradient and one down gradient well shall be installed at each earthen waste storage facility that requires groundwater monitoring. Existing wells may be utilized to meet this requirement if properly located and constructed.

3. All animal feeding operations previously covered under a general permit, an individual VPA permit, or a VPDES permit that required groundwater monitoring shall continue monitoring consistent with the requirements listed in this part regardless of where the animal feeding operations are located relative to the seasonal high water table.

4. At animal feeding operations where groundwater monitoring is required, the following conditions apply:

a. One data set shall be collected from each well prior to any waste being placed in the storage facility.

b. The static water level shall be measured prior to bailing well water for sampling.

c. At least three well volumes of groundwater shall be withdrawn immediately prior to sampling each monitoring well.

5. In accordance with subdivisions 2 and 3 of this subsection, the groundwater shall be monitored by the permittee at the monitoring wells as specified in Table 1 of Part I. Additional groundwater monitoring may be required in the approved nutrient management plan written for the animal feeding operation.

6. If groundwater monitoring results for any monitored parameter demonstrate potential noncompliance with this general permit related to the waste storage facility, then the permittee shall submit an approvable groundwater monitoring action plan that outlines appropriate measures to be taken to address the noncompliance. The groundwater monitoring action plan shall be submitted to the department within 30 days of obtaining the monitoring results.

7. The analysis of the groundwater samples for ammonia nitrogen and nitrate nitrogen shall be performed by a laboratory accredited under the Virginia Environmental Laboratory Accreditation Program (VELAP) in accordance with 1VAC30-46-20.

B. Site design, storage, and operations requirements.

1. Any liquid manure collection and storage facility shall be designed and operated to (i) prevent point source discharges of pollutants to state waters except in the case of a storm event greater than the 25-year, 24-hour storm and (ii) provide adequate waste storage capacity to accommodate periods when the ground is frozen or saturated, periods when land application of nutrients should not occur due to limited or nonexistent crop nutrient uptake, and periods when physical limitations prohibit the land application of waste.

2. Waste storage facilities constructed after December 1, 1998, shall not be located on a 100-year floodplain. For the purposes of determining the 100-year floodplain, a Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM), a FEMA Letter of Map Amendment (LOMA), or a FEMA Letter of Map Revision (LOMR) shall be used.

3. Earthen waste storage facilities constructed after December 1, 1998, shall include a properly designed and installed liner. Such liner shall be either a synthetic liner of at least 20 mils thickness or a compacted soil liner of at least one foot thickness with a maximum permeability rating of 0.0014 inches per hour. A Virginia licensed professional engineer or an employee of the Natural Resources Conservation Service of the U.S. Department of Agriculture with appropriate engineering approval authority shall certify that the siting, design, and construction of the waste storage facility comply with the requirements of this general permit. This certification shall be maintained on site.

4. At earthen waste storage facilities constructed below the seasonal high water table, the top surface of the waste must be maintained at a level of at least two feet above the water table.

5. All liquid waste storage facilities shall maintain at least one foot of freeboard at all times, up to and including a 25-year, 24-hour storm.

6. For new waste storage facilities constructed after November 16, 2014, the facilities shall be constructed, operated, and maintained in accordance with the applicable practice standard adopted by the Natural Resources Conservation Service of the U.S. Department of Agriculture and approved by the department. A Virginia licensed professional engineer or an employee of the Natural Resources Conservation Service of the U.S. Department of Agriculture with appropriate engineering approval authority shall certify that the siting, design, and construction of the waste storage facility comply with the requirements of this general permit. This certification shall be maintained on site.

7. The permittee shall notify the department's regional office at least 14 days prior to (i) animals being initially placed in the confined animal feeding operation or (ii) the utilization of any new waste storage facilities.

8. Semi-solid and solid waste shall be stored in a manner that prevents contact with surface water and groundwater. Waste that is stockpiled outside for more than 14 days shall be kept in a waste storage facility or at a site that provides adequate storage. Adequate storage shall, at a minimum, include the following:

a. Waste shall be covered to protect it from precipitation and wind;

b. Stormwater shall not run onto or under the stored waste;

c. A minimum of two feet separation distance to the seasonal high water table or an impermeable barrier shall be used under the stored waste. All waste storage facilities that use an impermeable barrier shall maintain a minimum of one foot separation between the seasonal high water table and the impermeable barrier. Impermeable barriers shall be constructed of at least 12 inches of compacted clay, at least four inches of reinforced concrete, or another material of similar structural integrity that has a minimum permeability rating of 0.0014 inches per hour (1X10-6 centimeters per second); and

d. For waste that is not stored in a waste storage facility or under roof, the storage site must be at least 100 feet from any surface water, intermittent drainage, wells, sinkholes, rock outcrops, and springs. For semi-solid and solid waste that is stored on an impermeable barrier and where any stormwater runoff is collected in the waste storage facility, the semi-solid and solid waste can be stored adjacent to the waste storage facility regardless of the location of the waste storage facility so long as any surface water, intermittent drainage, wells, sinkholes, rock outcrops, and springs are protected from runoff from the stored semi-solid and solid waste.

Semi-solid and solid waste that is stored on an impermeable barrier and where any stormwater runoff is collected in a waste storage facility is considered adequate storage and is therefore not required to be covered.

9. All equipment needed for the proper operation of the permitted animal feeding operations shall be maintained in good working order. The manufacturer's operating and maintenance manuals shall be retained for references to allow for timely maintenance and prompt repair of equipment when appropriate. The permittee shall periodically inspect for leaks on equipment used for land application of waste.

11. When the waste storage facility is no longer needed, the permittee shall close it in a manner that (i) minimizes the need for further maintenance and (ii) controls, minimizes, or eliminates, to the extent necessary to protect human health and the environment, the postclosure escape of uncontrolled leachate, surface runoff, or waste decomposition products to the groundwater, surface water, or the atmosphere. Prior to closure, the permittee shall notify the department of any plans to close a liquid waste storage facility. At closure, the permittee shall remove all waste residue from the animal waste storage facility. Removed waste materials shall be utilized according to the approved NMP.

C. Animal waste use and transfer requirements.

1. Animal waste generated by an animal feeding operation that is subject to this general permit shall not be applied to fields owned by or under the operational control of either the permittee or a legal entity in which the permittee has an ownership interest unless the fields are included in the approved nutrient management plan written for the animal feeding operation.

2. The permittee shall implement a nutrient management plan (NMP) developed by a certified nutrient management planner in accordance with § 10.1-104.2 of the Code of Virginia and approved by the Department of Conservation and Recreation and maintain the NMP on site.

(ii) the manager of one or more manufacturing, production, or operating facilities employing more than 250 persons or having gross annual sales or expenditures exceeding $25 million (in second-quarter 1980 dollars) if authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures;

b. For a partnership or sole proprietorship: by a general partner or the proprietor, respectively; or

c. For a municipality, state, federal, or other public agency: by either a principal executive officer or ranking elected official. For purposes of this section, a principal executive officer of a public agency includes (i) the chief executive officer of the agency or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency.

2. Reports and other information. All reports required by general permits and other information requested by the department shall be signed by a person described in Part II H 1 or by a duly authorized representative of that person. A person is a duly authorized representative only if:

a. The authorization is made in writing by a person described in Part II H 1;

b. The authorization specifies either an individual or a position having responsibility for the overall operation of the regulated facility or activity, such as the position of plant manager, operator of a well or a well field, superintendent, or a position of equivalent responsibility. A duly authorized representative may thus be either a named individual or any individual occupying a named position; and

c. The written authorization is submitted to the department.

3. Changes to authorization. If an authorization under Part II H 2 is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, a new authorization satisfying the requirements of Part II H 2 shall be submitted to the department prior to or together with any reports or information to be signed by an authorized representative.

4. Certification. Any person signing a document under Part II H 1 or 2 shall make the following certification: "I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to ensure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."

I. Duty to comply. The permittee shall comply with all conditions of this general permit and this chapter. Any noncompliance with this general permit or this chapter constitutes a violation of the State Water Control Law. General permit noncompliance is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or for denial of a permit renewal application. Compliance with this general permit during its term constitutes compliance for purposes of enforcement with the State Water Control Law.

J. Duty to reapply.

If the permittee wishes to continue an activity regulated by this general permit after the expiration date of this general permit, the permittee shall apply for and obtain a new permit. All permittees with a currently effective general permit shall submit a new application before the expiration date of the existing general permit unless permission for a later date has been granted by the board. The board shall not grant permission for applications to be submitted later than the expiration date of the existing general permit.

K. Bypass.

1. Prohibition. "Bypass" means intentional diversion of waste streams from any portion of a treatment works. A bypass of the treatment works is prohibited except as provided in this subsection.

2. Anticipated bypass. If the permittee knows in advance of the need for a bypass, the permittee shall notify the department promptly at least 10 days prior to the bypass. After considering its adverse effects, the department may approve an anticipated bypass if:

a. The bypass will be unavoidable to prevent loss of human life, personal injury, or severe property damage. "Severe property damage" means substantial physical damage to property, damage to the treatment works that causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. "Severe property damage" does not mean economic loss caused by delays in production; and

b. There are no feasible alternatives to bypass such as the use of auxiliary treatment works, retention of untreated waste, or maintenance during normal periods of equipment downtime. However, if bypass occurs during normal periods of equipment downtime or preventive maintenance and in the exercise of reasonable engineering judgment the permittee could have installed adequate backup equipment to prevent such bypass, this exclusion shall not apply as a defense.

3. Unplanned bypass. If an unplanned bypass occurs, the permittee shall notify the department as soon as possible, but in no case later than 24 hours, and shall take steps to halt the bypass as early as possible. This notification will be a condition for defense to an enforcement action that an unplanned bypass met the conditions in Part II K 2 a and b and in light of the information reasonably available to the permittee at the time of the bypass.

L. Upset. A permittee may claim an upset as an affirmative defense to an action brought for noncompliance. In any enforcement proceedings a permittee shall have the burden of proof to establish the occurrence of any upset. In order to establish an affirmative defense of upset, the permittee shall present properly signed, contemporaneous operating logs or other relevant evidence that shows:

1. That an upset occurred and that the cause can be identified;

2. That the permitted facility was at the time being operated efficiently and in compliance with proper operation and maintenance procedures;

3. That the 24-hour reporting requirements to the department were met; and

4. That the permittee took all reasonable steps to minimize or correct any adverse impact on state waters resulting from noncompliance with the permit.
