ART. IV. AGBICULTURAL, RB3ID8NTIAL, FLOOD PLAIN AND AQUIFB�t DI3TRICTS 3ection 404. AQUIFBR DI3TRICT. The purpose of this ordinance is to preserve the water quality of the Big Sioux Aquifer within the Joint Jurisdictional Area, protecting the development and use of land in a manner that will positively affect the quality of water within the areas designated Aquifer Secondarp Impact Areas, and preventing any use that would affect the water quality within the Aquifer Critical Impact Areas associated with the public wells that supply the City of Brookings. The Brookings City and County Commissions reco�nize ( 1 ) that residents of Brookings County rely exclusively on �round water for a safe drinking water supply and (2) that certain land uses in Brookin8s County can contaminate ground water particu- larly in shallow/surficisl aquifers. The purpose of the Aquifer Protection Overlay District is to protect public health and safetp by minimizing contamination of the shallow/surficial aquifers in the Joint Jurisdictional Area. It is the intent to accomplish this, as much as posaible, by public education and aecuring public cooperation. Appropriate land use regulationa will be imposed, however, which are in addition to those imposed in the underlying zoning districts or in other regulations. It is not the intent to grandfather in existing land uses which pose a serious threat to public health through potential contamination of public water supply well head areas. . 1 DEFINITIONS. a) Action.

Boundaries for the aquifer protection zones for the Aquifer Protection Overlay District are shown on published maps 4 entitled "Well Head Protection Area Maps, Brookings County Shallow Aquifer Map" dated May 1988 as drawn by Banner Associates. Sheets 3 and 4 of said maps are hereby adopted by reference as part of this ordinance as if the maps were fully described herein. The shallow/surficial aquifer boundary was mapped using data from the South Dakota Geological Survey and United States Geological Survey. The zone of contribution was mapped using an analytical technique outlined in the U.3. Environmental Protection Agency publication "Guidelines for Delineation of Well head Protection Areas, June, 1987 . " The Aquifer Protection Overlay District was divided into two zones. a) Zone A - Aquifer Critical Impact Zone. Zone A, the well head protection area, ia the zone of contribution mapped around all public water supply wells or well fields and includes land upgradient to the ten year time of travel boundary. ( 1 ) Permitted uses in Zone A, provided they meet appropriate Performance Standards outlined For Aquifer Protection Overlay Zones: a) Agriculture; b) Horticulture; c) Park, greenways or publiclp owned recreational areas; d) Necessary public utilities/facilities desiQned so as to prevent contamination of ground water. (2) Special Exceptions in Zone A: The following uses are permitted onlp under the terms of a special exception and must conform to provisions of the underlying zoning district and meet the Performanee Standards outlined for the Aquifer Protection Overlay Zones. aj Expansion of existing nonconforming uses to the extent allowed by the underlying district. The Board of Adjustment shall not grant approval unleas it finds such expansion does not pose greater potential contamination to ground water than the existing use. 5 ( 3 ) Prohibited Uses in Zone A: The following uses are expressly prohibited in Zone A: a) New feedlots installed after adoption of this ordinance; b) Disposal of solid waste except spreading of manure; c) Outside unenclosed stora�e of road salt; d) Disposal of anow containing de-icing chemicals; e) Processing and storage of PCB containing oils; f) Car washes ; g) Auto service, repair or painting facilities and junk or salvage yards; h) Disposal of radioactive waste; i ) Graveyards or animal burial sites; j ) Open burning and detonation sites; k) All other facilities involving the collection, handing, manufacture, use storage, transfer or disposal of any solid or liquid material or waste having a potentially harmful impact on ground water quality; 1 ) All uses not permitted or not permitted as special exceptions in Zone A. m) Fall application of nitrogen fertilizer except , spreading of manure. b) Zone B - Aquifer Secondary Impact Zones Zone B is established as the remainder of the mapped shallow/ surficial aquifer not included in Zone A plus contributing drainage areas, as delineated on the official copy of published maps representing aloping, adjacent lands not underlain by the aquifer fro� whieh surface water can flow direetly onto Zone A. This portion of the aquifer is being protected because ( 1 ) it is a valuable natural resource for future development, (2) it provides drinking water supply for individual households, ( 3 ) contamination is not justi- 6 fied, even though this area is not a public water supply wellhead and ( 4) contaminants could eventually reach Zone A. ( 1 ) Permitted Uses in Zone B: a) All uses permitted in the underlyin� zoning districts provided that they can aeet the Performance Standards as outlined for the Aquifer Protection Overlap Zones. (2) Special Exceptions in Zone B: a) All special exceptions allowed in underlying districts may be approved by the Board of Adjustment provided they can meet Perfor�ance Standards outlined for the Aquifer Protection Overlay Zones. ( 3) Prohibited Use in Zone B: The following use is expressly prohibited in Zone B: $) Fall application of nitrogen fertilizer except spreading of manure. c) Performanee Standards: In determining whether a permit should be granted, the City Engineer and/or the County Zoning Officer shall apply the following guidelines to determine the pos- sible impact of the proposed action on Zone A -Aquifer Critical Impact Zone and/or Zone B - Secondarp Iapact Zone. The following standards shall apply to Agricultural land uses in Zones A and B of the Aquifer Protection Overlay Districts : ( 1 ) New or replaeement septic tanks and associated drain fields for containment of hwnan or animal wastes must conform with regulations established by the State Department of Water and Natural Resources. (2) Any facility involving the collection, handling, manufacture, use, storage, transfer or disposal of any solid or liquid material or wastes, exeept for spreading of manure, in excess of 1000 pounds and/ or 100 gallons which has the potential to contaa- inate ground water shall be regulated aceording to SDCL Chapter 74 :03 : 28 - Underground 3torage Tanks or SDCL Chapter 74: 03 : 30 - Above Ground Stationary 7 Storage Tanks. Pipes installed to carry diluted chemicals for chemigation are exe�pted and storage of liquid fertilizer for chemigation is allowed as long as a secondary containment system is used. Secondary containment for tanks used for chemiga- tion must be in place by July 1 , 1990. ( 3) Open liquid waste ponds containing materials referred to in ( 2) above will not be permitted without a secondary containment system except for community wastewater lagoons. Agricultural waste storage ponds are permitted but must be con- structed in conformance with 8oi1 Conservation Service South Dakota Engineering Standard, Waste Storage Ponds 425 . (3ee Appendix 1 ) (4 ) Storage of petroleum products in quantities exceeding fifty-five (55) gallona at one locality in one tank or series qf tanks must be in elevated tanka; such tanks must have a secondary contain- ment system noted in (2) above where it is deemed necessary by the County Zoning Office. ( 5 ) Discharge of industrial process water on site is prohibited without County Zoning Office approval.

(See Appendix 2) ( 7 ) Auto service, repair or painting facilities and junk or salvage yards in Zone B shall meet all State and Federal standards for storage, handling and disposal of petroleum products and shall properly dispose of all other potentially hazardous waste materials. . (8) An acceptable contingency plan for all permitted facilitiea must be prepared and on file in the City/ County Zoning Office for preventing hazard- ous materials from contaminating the shallow/ surficial aquifer should floods, fire and other natural catastrophes or equipment failure occur: a) For flood control , all underground facilities shall include but not be limited to a aonitor- ing system and secondary standpipe above the 100 year flood control level, for monitoring and recovery. For above ground facilities, an impervious dike, above the 100 year flood level and capable of containing 110 percent of the largest volume of storage, will be pro- 8 vided with an overflow recovery catchment area (sump) . b) For fire control, plans shall include but not be limited to a safe fire fightina procedure, a fire retardant system and provide for deal- ing safely with both health and technical hazards that may be encountered by disaster control personnel in combating fire. Hazarda to be considered are overhead and buried electrical .lines, pipes, other buried objects and other hazardous liquids, ehemicals or open flames in the immediate vicinity. c) For equipment failures, plans shall include but not be limited to: Below ground level, removal and replacement of leakin� parts, a leak detection system with monitoring and an overfill protection system. Above ground level, liquid and leaching monitoring of primary containment systems, their replacement or repair and cleanup and/or repair of the impervious surface. d) For any other natural or man-caused disasters occurring, the owner and/or operator shall report all incidents involving liquid or chemical material in an endangerment of the health and /or safety of either disaster personnel and/or the public in general. e) Agricultural operations are exempted from this section unless they store chemieals that are on the Superfund Amendments and Reauthoriza- tion Act of 1986 (SARA Title III ) extremely hazardous substance list over the threshold planning quantity at any one time. (9ee Appendix 4j f) The County Zoning Office and DWNR shall be informed within 24 hours of all leaks and spills of materials that might potentially contaminate ground water. (9 ) Sinee it is known that improperly abandoned wells can become a direct conduit for contamination of ground water by surface water, all abandoned wells ahould be plugged in conformance with South Dakota Well Construction 8tandards, Chapter 74:02:04:67- 70. 9 d) The following standards shall apply to zoned areas exeluding ASricultural in Zones A and B of the Aquifer Protection Overlay Districts : ( 1 ) Septic tanks and associated drain fields for containment of human or animal wastes must have approval of the State Department of Water and Natural Reaources. (2) The storage and retention of any solid or liquid hazardous material which has the potential to adversely effect the water quality of the aquifer must have secondary containment facilities whieh are easily inspected and whose purpose is to intercept any leak or discharge from the pri�ary containment vessel or structure. Underground tanks or buried pipes carrying sueh materials must have double walls and inspectable sumps. ( 3) No open liquid waste ponds containing materials in ( 2) above will be permitted. (4) Storage of petroleum products in quantities exceeding fifty-five gallons at one locality in one tank or series of tanka must meet the requirements of (2) above.
