MONITORING AND REPORTING PROGRAM NO. R5-2014-0006 FORWARD INC. AND REPUBLIC SERVICES INC. FORWARD CLASS II LANDFILL SAN JOAQUIN COUNTY 18 Quality Protection Standard other than annual update of the concentration limits shall be submitted in a report for review and approval. The report shall: a. Identify all distinct bodies of surface and ground water that could be affected in the event of a release from a waste management unit or portion of a unit. This list shall include at least the uppermost aquifer and any permanent or ephemeral zones of perched groundwater underlying the facility. b. Include a map showing the monitoring points and background monitoring points for the surface water monitoring program, groundwater monitoring program, and the unsaturated zone monitoring program. The map shall include the point of compliance in accordance with Title 27, section 20405. c. Evaluate the perennial direction(s) of groundwater movement within the uppermost groundwater zone(s). d. Include a proposed statistical method for calculating concentration limits for monitoring parameters and constituents of concern that are detected in 10% or greater of the background data (naturally-occurring constituents) using a statistical procedure from Title 27, section 20415(e)(8)(A-D)] or section 20415(e)(8)(E). e. Include a retesting procedure to confirm or deny measurably significant evidence of a release pursuant to Title 27, section 20415(e)(8)(E) and section 20420(j)(1-3). The Water Quality Protection Standard shall be certified by a California- registered civil engineer or geologist as meeting the requirements of Title 27. If subsequent sampling of the background monitoring point(s) indicates significant water quality changes due to either seasonal fluctuations or other reasons unrelated to waste management activities at the site, the Discharger may request modification of the Water Quality Protection Standard. The Discharger proposed the methods for calculating concentration limits in the 2011 Concentration Limit Update Report. Groundwater limits are calculated using intra-well tolerance limits and surface water limits are based on inter- station tolerance limits. All tolerance limits are based on a Type I error rate of alpha – 0.01 and a coverage of 95%. The Water Quality Protection Standard shall be updated every two years beginning in 2014 for each monitoring well using new and historical monitoring data.
