The application of the ADC over the refuse was good. However, several of the tarps had large tears in them,that appeared to nulify the provision of the required daily cover over the compacted refuse. Repair the tears on the tarps, so the refuse may be covered adequately and/or apply soil or other approved ADC material to cover the compacted refuse at the work face. x 20921 -Gas Monitoring and Control Comments: CalRecycle staff and the LEA measured methane gas levels at three of the landfill's gas migration monitoring probes(GP-9, GP-11 and GP-12)using the LEA's Landtec GEM-2000 instrument. The obtained methane readings in probes GP-9 and GP-12 were 0.00%. However,the methane gas readings obtained in probe GP-11 were as follows: @shallow depth =7.3%, @medium depth = 8.2%, and 0.00%@the deep probe. Additionally, review of the operator's May 2010 monitoring program for probe GP-11 indicated the following methane gas levels: @shallow depth=38.0%, @medium depth=49.0%and @the deep probe= 13.4%. CalRecycle staff was informed that methane gas levels in the*monitoring probe in March 2010 were also greater than the regualtory limit of 5.00%. The obtained methane gas readings at the shallow and medium depths of the monitoring probe were above the required limit of 5.00%at the permitted property boundary.The records of the monitoring program for March and May 2010 also showed that methane gas levels in GP-11 were above the regulatory limit. The obtained and recorded levels of the methane gas in the monitoring probe are a violation of 27 CCR, Section 20919(a)(2). The operator shall immediately follow the requirements specified in 27 CCR, Section 20937, and within 60 days of detection, implement a remediation plan that has been approved by the Enforcement Agency(EA)and CalRecycle(formerly CIWMB).
