(1) These operations shall be inspected within 30 days of the effective date of this regulation. Thereafter, these operations shall be inspected by the EA at least once quarterly to verify compliance with minimum standards, unless the EA approves, with Department concurrence, a reduced inspection frequency. The EA may approve a reduced inspection frequency only if it will not pose an additional risk to public health and safety or the environment, but in no case shall the frequency be less than once per calendar year. [Note: See section 18083(a)(3) for additional EA and Department requirements regarding the approval or denial of request for reducing the frequency of inspections.]
