16.50.340 Development Standards for Specific Activities in Critical Aquifer Recharge Areas.
(1) Storage Tanks. All storage tanks proposed to be located in a critical aquifer recharge area must comply with local building code requirements and must conform to the following requirements:
(a) Underground Tanks. All new underground storage facilities proposed for use in the storage of hazardous substances or hazardous wastes shall be designed and constructed so as to:
(i) prevent releases due to corrosion or structural failure for the operational life of the tank;
(ii) be protected against corrosion, constructed of noncorrosive material, steel clad with a noncorrosive material, or designed to include a secondary containment system to prevent the release or threatened release of any stored substances; and
(iii) use material in the construction or lining of the tank that is compatible with the substance to be stored.
(b) Aboveground Tanks. All new aboveground storage facilities proposed for use in the storage of hazardous substances or hazardous wastes shall be designed and constructed so as to:
(i) not allow the release of a hazardous substance to the ground, ground waters, or surface waters;
(ii) have a primary containment area enclosing or underlying the tank or part thereof; and
(iii) have a secondary containment system either built into the tank structure or a dike system built outside the tank for all tanks.
(2) Vehicle Repair and Servicing. Vehicle repair and servicing must be conducted over impermeable pads and within a covered structure capable of withstanding normally expected weather conditions. Chemicals used in the process of vehicle repair and servicing must be stored in a manner that protects them from weather and provides containment should leaks occur.
(3) Spreading or Injection of Reclaimed Water. Water reuse projects for reclaimed water must be in accordance with the adopted water or sewer comprehensive plans that have been approved by the Departments of Ecology and Health.
(a) Surface spreading must meet the ground water recharge criteria given in Chapter 90.46.080 RCW and Chapter 90.46.010(10).
(b) Direct injection must be in accordance with the standards developed by authority of Chapter 90.46.042 RCW.
(4) State and Federal Regulations. The uses listed in Table 16.50.4 below shall be conditioned as necessary to protect critical aquifer recharge areas in accordance with the applicable state and federal regulations.
