A. Compliance with HWMP: All permit holders shall handle and control hazardous wastes in accordance with the provisions of the hazardous wastes management plan (HWMP) approved by the County.
B. Records Kept: Records of monitoring, inspections and sampling results produced pursuant to a monitoring plan that is a part of an HWMP approved by the County shall be kept and made available for inspection at all times.
C. Unauthorized Release of Hazardous Wastes:
1. As soon as any hazardous waste handler has knowledge of any unauthorized release, that handler shall report the incident to the County immediately and, in all cases, within one hour after the release is discovered. Any emergency variation from the HWMP on file shall be immediately reported to the County. The notification, as required hereunder, shall be reported to the Lyon County Sheriff's office which will notify the appropriate County personnel.
2. In the event of an unauthorized release, the County may require:
a. That the hazardous wastes handler conduct monitoring to establish whether there is environmental contamination as a result of the release;
b. Removal of the hazardous wastes and contaminated media; and/or
c. That the hazardous waste handler pay the costs of a consultant of the County's choosing to evaluate testing and removal activities.
D. Closure Plan: As part of the application for a hazardous waste permit, the applicant shall file a plan satisfactory to the County for ultimate closure of the facility. The closure plan shall include:
1. A detailed plan for decontamination and restoration of the facility site, including description of methods to be used, estimates of costs, verified by independent consultants, and any other data which would assist the County in determining the efficacy of the closure plan; and
2. An irrevocable letter of credit, irrevocable bond or other irrevocable surety acceptable to County in a sum sufficient to effect the decontamination and restoration proposed in the detailed plan.
The permittee shall implement its closure plan when it permanently ceases operations under the hazardous waste permit or when operations have ceased for a period of six (6) months, which time shall be deemed to be a permanent cessation of operations unless it be shown to the satisfaction of the County that the cessation is temporary and that the operations will resume at some reasonable time satisfactory to the County.
A permittee may not escape responsibility for implementing the closure plan by sale or other disposition of the facility. Any subsequent permittee holding a hazardous waste permit for the same site also is responsible for implementing the closure plan at the time of ultimate closure. (Ord. 355, 5-2-91)
