(2) "Bypass" means the intentional diversion of waste streams from any portion of a treatment facility.
(3) "Catastrophic" means a tornado, hurricane, earthquake, flood, or other extreme condition that causes an overflow from a required waste retention structure.
(4) "Certification" means:
(a) The acknowledgment by a local conservation district that a dairy producer has constructed or otherwise put in place the elements necessary to implement his or her dairy nutrient management plan; and
(b) The acknowledgment by a dairy producer that he or she is managing dairy nutrients as specified in his or her approved dairy nutrient management plan.
(5) "Chronic" means a series of wet weather events that precludes the proper operation of a dairy nutrient management system that is designed for the current herd size.
(6) "Conservation commission" or "commission" means the conservation commission under chapter 89.08 RCW.
(7) "Conservation districts" or "district" means a subdivision of state government organized under chapter 89.08 RCW.
(8) "Concentrated dairy animal feeding operation" means a dairy animal feeding operation subject to regulation under this chapter which the director designates under RCW 90.64.020 or meets the following criteria:
(a) Has more than seven hundred mature dairy cows, whether milked or dry cows, that are confined; or
(b) Has more than two hundred head of mature dairy cattle, whether milked or dry cows, that are confined and either:
(i) From which pollutants are discharged into navigable waters through a man-made ditch, flushing system, or other similar man-made device; or
(ii) From which pollutants are discharged directly into surface or ground waters of the state that originate outside of and pass over, across, or through the facility or otherwise come into direct contact with the animals confined in the operation.
(9) "Dairy animal feeding operation" means a lot or facility where the following conditions are met:
(a) Dairy animals that have been, are, or will be stabled or confined and fed for a total of forty-five days or more in any twelve-month period; and
(b) Crops, vegetation forage growth, or postharvest residues are not sustained in the normal growing season over any portion of the lot or facility. Two or more dairy animal feeding operations under common ownership are considered, for the purposes of this chapter, to be a single dairy animal feeding operation if they adjoin each other or if they use a common area for land application of wastes.
(10) "Dairy farm" means any farm that is licensed to produce milk under chapter 15.36 RCW.

(16) "Upset" means an exceptional incident in which there is an unintentional and temporary noncompliance with technology-based permit effluent limitations because of factors beyond the reasonable control of the dairy. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.
(17) "Violation" means the following acts or omissions:
(a) A discharge of pollutants into the waters of the state, except those discharges that are due to a chronic or catastrophic event, or to an upset as provided in 40 C.F.R. Sec. 122.41, or to a bypass as provided in 40 C.F.R. Sec. 122.41, and that occur when:
(i) A dairy producer has a current national pollutant discharge elimination system permit with a wastewater system designed, operated, and maintained for the current herd size and that contains all process-generated wastewater plus average annual precipitation minus evaporation plus contaminated stormwater runoff from a twenty-five year, twenty-four hour rainfall event for that specific location, and the dairy producer has complied with all permit conditions, including dairy nutrient management plan conditions for appropriate land application practices; or
(ii) A dairy producer does not have a national pollutant discharge elimination system permit, but has complied with all of the elements of a dairy nutrient management plan that: Prevents the discharge of pollutants to waters of the state, is commensurate with the dairy producer's current herd size, and is approved and certified under RCW 90.64.026;
(b) Failure to register as required under RCW 90.64.017;
(c)(i) Until July 1, 2011, failure to keep for a period of three years all records necessary to show that applications of nutrients to the land were within acceptable agronomic rates, unless otherwise required by law; and
(ii) Beginning July 1, 2011, failure to keep for a period of five years all records necessary to show that applications of nutrients to the land were within acceptable agronomic rates;
(d) The lack of an approved dairy nutrient management plan by July 1, 2002; or
(e) The lack of a certified dairy nutrient management plan for a dairy farm after December 31, 2003.
