Current through Register 2024 Notice Reg. No. 28, July 12, 2024
An owner or operator required to establish a detection
					 monitoring program under this article shall, at a minimum, discharge the
					 responsibilities specified in subsections (a) through (f) of this section
					 concerning monitoring of air and soil-pore gas.
(a) The owner or operator shall assure that
				  monitoring and corrective action measures necessary to achieve compliance with
				  the environmental protection standard under section
				  66264.702 are taken as specified
				  in the permit or in an order issued by the Department.
(b) The owner or operator of a regulated unit
				  that contains hazardous waste or discarded hazardous material that contains a
				  volatile toxic substance or a hazardous material that can become airborne, or
				  that can decompose or react to form a volatile toxic substance or toxic gas,
				  shall follow methods prescribed by the Department to provide for representative
				  sampling and analysis of air upwind and at the disposal area, and of soilpore
				  gas at monitoring points under section
				  66264.705, established by the
				  owner or operator to the satisfaction of the Department. Vapor and gas
				  monitoring wells shall be covered with collection chambers approved by the
				  Department. The owner or operator shall provide, inside the collection
				  chambers, probes or equivalent methodologies that actively sense the
				  concentration of substances specified by the Department. If specified by the
				  Department, the owner or operator shall provide instrumentation that provides
				  continuous recording of concentrations of substances in open air and in the
				  atmosphere of vapor wells.
(c)
				  Samples will be analyzed for those substances specified in the permit. Unless
				  the Department specifies in the permit parameters and constituents for which
				  samples described in subsection (b) of this section shall be analyzed, the
				  owner or operator shall analyze the samples to determine the concentration of
				  all constituents that cause waste at the regulated unit to be hazardous waste.
				  The Department will specify for the regulated unit the location and frequency
				  of monitoring and the type of statistical analysis that will be used. The owner
				  or operator shall submit a report to the Department that indicates the results
				  of the analysis and the concentrations of constituents in the air and soil-pore
				  gas sampled. The report shall be submitted to the Department within 30 days of
				  the date analyses are completed.
(d) If the owner or operator determines that
				  there is an increase of hazardous constituents at any monitoring point under
				  section 66264.705, the owner or operator
				  shall:
(1) notify the Department of this
				  finding in writing within seven days of the date such determination is made.
				  The notification shall indicate what constituents have shown statistically
				  significant increases;
(2) within
				  90 days of the determination, submit to the Department an application for a
				  permit modification to modify the facility or operating practices at the
				  facility.
