Corral Hollow Landfill—G° iolation Page 2 of 3 On May 23, 1997,PHS-EHD generated a letter directing your department to conduct an Air Solid Waste Assessment Test(SWAT). The results of the Air SWAT were received by PHS- EHD on January 26, 1998. The results were reviewed by Linda Turkatte of PHS-EHD and forwarded to Tim Crisp, a staff member of the California Integrated Waste Management Board (CIWMB). Tim Crisp reviewed the results and indicated that landfill gas control needs to be implemented at the site. On January 29, 1998, PHS-EHD generated a letter directing your department to submit a plan to implement gas control at this site. On March 25, 1998, Linda Turkatte of PHS-EHD noted on the inspection report that the gas levels at the boundary were above the compliance levels. Linda also noted that the work plan for corrective action had not been received and was over due (copy enclosed). The PHS-EHD did not receive the plan. On November 20, 1998, during a quarterly inspection conducted by John Yoakum of PHS-EHD, it was noted that the gas levels at the boundary were a violation (above 5%). On June 21, 2000, I conducted a site inspection with Gino Yekta of the CIWMB. During the inspection,the perimeter gas wells were sampled for the presents of methane gas. The test results indicated wells# 1, 2, 3, and 6 were above 5%methane by volume at the boundary. This is a violation of Title 27, CCR, Section 20919.5,which states-that"the owners and operators of all landfills must ensure that the concentration of methane gas does not exceed the Lower Explosive Limit (5%by volume) for methane at the facility boundary." If methane gas levels exceed the 5% limit,the CCR requires the owner or operator to: 1. Immediately take all necessary steps to ensure protection of human health and notify the LEA. 2. Within 7 days of detection,place in the operating record, the methane gas levels detected and a description of the steps taken to protect human health. 3. Within 60 days of detection, implement a remediation plan for the methane gas releases, place a copy of the plan in the operating record, and notify the LEA that the plan has been implemented. This facility is and remains in a state of non-compliance with this department and Title 27, CCR. The PHS-EHD directs your department to comply with Title 27, CCR, Section 20937(a)(5) (provided). Submit gas control system design plans for review. The gas control system plans should be submitted in duplicate to allow PHS-EHD to forward a copy to the CIWMB for concurrence. (a) When the results of gas monitoring indicate concentrations of methane in excess of the compliance levels required by§20921(a), the operator shall: (1) Take all immediate steps necessary to protect public health and safety, and the environment. (2)Notes the EA in writing within five(5) working days of learning that compliance levels have been exceeded, and indicate what has been done or is planning to be done to resolve the problem. (3) Verify accuracy of results by reviewing the following: (A) probe readings; (B) possible liquid interference; (C) control well influence;and (D) barometric pressure effects.
