Cal. WAT § 13273.5

Notwithstanding Section 13273, a small city which operates a Class III solid waste disposal site is not required to submit a solid waste water quality assessment test report pursuant to Section 13273 if the city has a population of less than 20,000 persons, the solid waste disposal site receives less than 20,000 tons of waste per year, the water table of the highest aquifer under the disposal site is 250 or more feet below the base of the disposal site and the water in the highest aquifer is not potable, and the site receives less than an average of 12 inches of rainfall per year.

This section applies only if the disposal site is operational and has been granted all required permits as of January 1, 1991, if the site is located in Kings County, and if the city has completed an initial solid waste water quality assessment test and a solid waste air quality assessment test which establish that no significant air or water contamination has occurred, and, in that event, the city shall be exempted from conducting further assessment tests for seven years, or any longer time specified by the regional board, after the date of the initial assessment tests.
