(a) The board shall adopt regulations that are consistent with Section 40055 governing the monitoring and control of the subsurface migration of landfill gas.

(b) The board shall consult with the state water board, the State Air Resources Board, and the California Air Pollution Control Officers Association to ensure that the regulations do not conflict with any regulations adopted by the state water board and the State Air Resources Board or air pollution control districts and air quality management districts.

(c) The regulations adopted by the board pursuant to subdivision (a) shall establish monitoring and control standards, based on the potential of the waste to generate landfill gas, as determined by the board, and shall require owners and operators of disposal sites or disposal facilities to report monitoring data and to perform, or cause to be performed, site inventories and evaluations of disposal sites or disposal facilities for the subsurface migration of landfill gas.

(d) If an owner or operator of a disposal site or disposal facility is in compliance with requirements of the air pollution control district or the air quality management district within whose jurisdiction the disposal site or disposal facility is located, the owner or operator shall be deemed to be in compliance with this section and with any regulations adopted by the board pursuant to this section.
