(11) AFO operations existing as of April 1, 1999 and proposing to construct/expand an animal waste containment structure in order to prevent waste/wastewater discharge or run-off to waters of the State may be considered exempt from location buffer distances specified in this Chapter by the Director if the Director or his designee determines in writing that the additional/expanded structures are necessary to assure the protection of water quality and that there is not a feasible location alternative.

(12) Location buffer distances do not apply to confinement buildings, settling basins, holding ponds, sumps or other animal waste containment structures existing prior to April 1, 1999 nor do they apply to structures existing as of April 1, 1999 when a registration modification is required due to a change in ownership.

(13) Location buffer distances from an existing occupied dwelling, church, school, hospital, park, or property line shall not apply if the existing occupied dwelling, church, school, hospital, or park is owned by owners/operators of the animal waste management system, if the adjoining property owner consents in writing through a dated, notarized document, if the adjoining property contains a deed restriction notifying the owner of the possibility of nearby AFOs, or if the area is specifically zoned for the construction and operation of CAFOs by the controlling elected governmental authority.

(14) Location buffer distances do not apply to AFO waste/wastewater storage/treatment structures in existence, or where full site preparation is complete and utility infrastructure is installed and is documented in writing, as of April 1, 1999, or to AFO waste/wastewater storage/treatment structures constructed in accordance with the requirements of this Chapter after April 1, 1999 that are completed, replaced, repaired, modernized, reconstructed, and/or refurbished on the pre-existing site/location according to NRCS technical standards and guidelines to pre-existing size and operational status provided the resultant waste/wastewater storage/treatment structure is no closer to the nearest existing occupied dwelling, church, school, hospital, park, intermittent streams, ponds, lakes, springs, or sinkholes, or PWS, ONRW, or OAW classified/designated waters, wells, and water supplies, or property line than it was prior to the work on the waste/wastewater storage/treatment structure commencing.

(15) Location buffer distances do not apply to AFO confinement buildings in existence, or where full site preparation is complete and utility infrastructure is installed and is documented in writing, as of April 1, 1999, or to AFO confinement buildings constructed in accordance with the requirements of this Chapter after April 1, 1999 that are completed, replaced, repaired, modernized, reconstructed, and/or refurbished on the pre-existing site/location to current industry design standards according to NRCS technical standards and guidelines provided the resulting confinement building is no closer to the nearest existing occupied dwelling, church, school, hospital, park, intermittent streams, ponds, lakes, springs, or sinkholes, or PWS, ONRW, or OAW classified/designated waters, wells, and water supplies, or property line than it was prior to the work on the confinement building commencing.

(16) Location buffer distances do not apply to confinement buildings, settling basins, holding ponds, sumps or other animal waste containment structures under significant, active construction in accordance with the requirements of this Chapter as of April 1, 1999 provided all earthwork and construction/building is complete as of August 1, 1999 or an alternate completion date approved by the Director or his designee in writing, and the facility is ready to be operated according to NRCS technical standards and guidelines and the requirements of this Chapter.

(17) Unless required by the Director or his designee in writing as conditions warrant on an individual facility, programmatic, or categorical basis to ensure the protection of water quality and minimization of odors to the maximum extent practicable, the requirement for AFOs to maintain buffer distances contained in this Chapter shall not apply to right-of-ways (ROWs) or easements for energy transmission or transportation (e.g. power lines, gas or water pipelines, roads, etc.). The Director or his designee may exempt in writing as conditions warrant on an individual facility, programmatic, or categorical basis the requirement to maintain buffer distances contained in this Chapter for personal pets, veterinary offices, animal hospitals, municipal zoos, etc. small concentrations or collections of animals, or confined animals, and animals subject to specific zoning or siting restrictions by a municipality or other governmental body.

(18) A subsurface investigation for earthen holding pond, pit, sump, treatment lagoon, or other earthen storage/containment structure suitability and liner requirements shall be a component of the system designee and shall be performed by the owner/operator under the supervision of and certified by a QCP, and may consist of auger holes, dozer pits, or backhoe pits at a depth to the extent necessary to determine adequacy of the specific site for waste storage. The subsurface investigation must extend at least two feet below the planned bottom grade. Subsurface investigation in soils underlain by the Demopolis or Mooreville Chalk formations of the Selma Chalk group in the Blackland Prairie major land resource area may terminate at a depth of 1 foot below the surface of the chalk [Reference:

(1) Geologic Map of Alabama, 1988, Geologic Survey of Alabama, Michael W. Szabo and Charles W. Copeland, Jr., and

(2) Land Resource Regions and Major Land Resource Areas of the United States, USDA-NRCS, SCS, Agricultural Handbook 296, MLRA 135, Alabama, Mississippi, and Arkansas Blackland Prairie]. A detailed, comprehensive geologic investigation for suitability of the site that meets or exceeds NRCS technical standards and guidelines must be performed for proposed sites in karst topography. In those situations where testing performed during the initial on-site subsurface investigation is not conclusive, the owner/operator shall conduct additional subsurface investigation as necessary and provide documentation certified by a QCP to ensure conformance with NRCS technical standards and guidelines or other additional standards required by the Director or his designee to ensure the protection of water quality. Unless relevant information is available to the contrary, compliance with this provision during design and construction of the facility will normally demonstrate that no hydrologic connection exists at the particular site.

(19) All WMSPs shall be developed to meet or exceed NRCS technical standards and guidelines and address operation of the lagoon, waste storage ponds/sumps, and other waste storage facilities, and the location, amount, and timing of land application of wastes with respect to the nutrient uptake cycle of the vegetation on the land application site(s), minimization of odors to the maximum extent practicable, and minimization of potential disease vectors and nuisance pests.

(20) Unless the AFO owner/operator contracts in writing with a valid CAWV for all waste generated, or the owner/operator properly sells or gives away in good faith the waste to another person, the comprehensive waste management system BMPs for the entire farm, facility, or operation must include written agreements for use of all land application sites with documentation that adequate land application area is readily available. If the waste is sold or given away in good faith, the owner/operator or CAWV shall retain detailed, complete records of the transaction and provide the receiver of the waste information explaining the requirements of this Chapter. AFO waste management system BMPs must meet or exceed NRCS technical standards and guidelines. A CAFO WMSP must be prepared by a QCP and must meet or exceed NRCS technical standards and guidelines. The Department may require proof of land ownership, contractual agreements, or written permission for use of land as a land application site.

(21) All AFOs shall implement effective management procedures to the maximum extent practicable to keep dry wastes under roof or effective cover and to minimize manure from the facility coming into contact with stormwater or other water or wastewater source (other than de minimus inputs as determined by the Department) at any time during production, handling/spillage, storage, treatment, transport, or other activity prior to proper land application which meets or exceeds NRCS technical standards and guidelines.

(22) Unless an alternate date is approved in writing by the Director or his designee, after April 1, 1999, all AFO lagoons and other waste storage/treatment facilities, separately or collectively/cumulatively, shall be designed, constructed, operated, and maintained to ensure sufficient storage volume to contain all dry/wet waste and wastewater, to contain contaminated stormwater resulting from runoff generated by a 25-year, 24-hour storm event, to contain uncontaminated stormwater (that cannot be separated/segregated from contaminated runoff) resulting from runoff generated by a 25-year, 24-hour storm event, and to maintain an additional minimum safety margin of at least 12 inches freeboard to prevent discharges to groundwater or surface water. Operating storage volume shall be sufficient to contain/retain all dry/wet waste and wastewater and contaminated stormwater during extended periods when waste/wastewater cannot be properly land applied during the growing season at agronomic rates due to adverse climatological or seasonal conditions (generally late fall, winter, and early spring months).

(23) All AFOs shall implement effective management procedures at all times to properly collect, manage, store, treat, transport, and dispose domestic sewage and domestic wastewater onsite or offsite in a manner that meets or exceeds NRCS technical standards and guidelines and the requirements of the Department and the ADPH.

(24) Unless extended in writing by the Director or his designee, no later than January 1, 2003, all AFOs and CAFOs in the North Alabama Area as designated in NRCS technical standards and guidelines shall implement provisions to provide for a minimum of 180 days waste/wastewater storage/retention/holding capacity and/or Department accepted management procedures that meet or exceed NRCS technical standards and guidelines to ensure effective water quality protection during periods when land application or other approved disposal alternatives are not available. After December 1, 2000, new or expanding AFOs and CAFOs in the North Alabama Area shall implement this 180 day permanent/temporary storage requirement prior to commencing initial operation and/or expanded operations.

(a) Unless extended in writing by the Director or his designee, no later than January 1, 2003, all AFOs and CAFOs in the South Alabama Area as designated in NRCS technical standards and guidelines, shall implement provisions to provide for a minimum of 120 days waste/wastewater storage/retention/holding capacity and/or Department accepted management procedures that meet or exceed NRCS technical standards and guidelines to ensure effective water quality protection during periods when land application or other approved disposal alternatives are not available. After December 1, 2000, new or expanding AFOs and CAFOs in the South Alabama Area shall implement this 120 day permanent/temporary storage requirement prior to commencing initial operation and/or expanded operations.

(25) After December 1, 2000, construction of new or expanded manure storage pits and/or new waste/wastewater storage ponds at new, expanding, or existing AFOs or CAFOs are prohibited unless the owner/operator submits in writing an affirmative demonstration acceptable to the Director or his designee that the use of new or expanded manure storage pits and/or new waste storage ponds will be protective of water quality and will provide for the minimization of odors to the maximum extent practicable. Approval of the use of new or expanded manure storage pits and/or new or expanded concentrated waste storage ponds, if granted, shall be made in writing by the Director or his designee.

(26) Eligibility for alternate or modified buffer requirements for new or expanding AFO facilities as provided in Rule 335-6-7-.20(11), (12), (13), (14), (15), (16), (17), and (27), or other applicable rules, where construction commenced, is continuing, or resumes after December 1, 2000, must be approved in writing by the Director or his designee. Adequate, dated records documenting eligibility for alternate or modified buffer requirements claimed or applied by an AFO owner/operator for new or expanded facilities where construction was ongoing as of April 1, 1999 or construction commenced after April 1, 1999, and construction was completed prior to December 1, 2000, as provided in Rule 335-6-7-.20(11), (12), (13), (14), (15), (16), (17), and (27), or other applicable rules, must be witnessed or notarized and submitted to the Department prior to June 1, 2001.

(27) Unless otherwise approved by the Director or his designee for cause in writing, notwithstanding any other provision of this Chapter, existing or previously constructed/operated AFOs or AFOs constructed after April 1, 1999, that are inactive, idle, or closed, that have not registered and do not confine greater than 50 animal units during any 36 month period will not be considered existing facilities, but are/will be considered as expanding facilities for the application of buffer requirements and other requirements of this Chapter at the time animal confinement greater than 50 animal units resumes.
