necessary equipment and specialists, and the available capacity and location of needed treatment, storage, and disposal services.

(b)A schedule for implementation of the proposed corrective action program based upon the potential risks to human health and the environment, ground water use and contamination considerations, extent and nature of the contamination, and availability of treatment and/or disposal capacity for the wastes to be removed.

(4)Implementation of Corrective Action. The facility owner and/or operator shall initiate corrective action immediately upon the Department's approval of their corrective action plan and approval of the individual actions to be taken. The owner/operator shall propose, and, upon Department approval, take any interim measures necessary to ensure protection of human health and the environment based upon the time required to develop and implement long-term corrective actions, the threat to water resources, and weather conditions that may cause pollutants to be released or migrate from the facility site.

(5)Completion of Corrective Action. The facility owner/operator shall continue corrective action and assessment monitoring until the Department finds that successful corrective action has occurred.

3.Standards For Ground And Surface Water Data Evaluation And Reporting. Validation of the data from the sampling of the monitoring network is required to ensure that the data is reliable and provides a valid analysis of the ground and surface water quality in the vicinity of the solid waste facility. The results of the data validation procedures must be included in the monitoring reports for the solid waste facility to verify the accuracy and precision of the reported results, and account for anomalous results.

A.Data Validation. Unless otherwise approved by the Department, the following data validation methods must be conducted and the results included in the monitoring report.

(1)Verification that the chain of custody for each sample is continuous.

(2)Verification that all sample holding times were met.

(3)Calculation and tabulation of the ratio between Total Dissolved Solids and Specific Conductance. All samples for which this ratio falls outside the range of 0.55-0.75 must be identified in the report.

(4)Calculation and tabulation of the relative percent difference for all duplicate samples using the formula: [|S-D|/{S+D/2}](100) where S= sample value and D=duplicate value. Relative percent difference should be calculated only where both sample and duplicate values are greater than 5 times the practical quantitation limit of the analyte. All samples for which the relative percent difference exceeds 10% must be identified in the report.

(5)Beginning with the fifth analysis for each parameter, identification and tabulation of all results which fall outside of the historical range for the given sample point. This includes ground water elevations and field parameters.

(6)Identification of all parameters present in equipment blanks.

(7)Identification of all parameters present in trip blanks.

(8)Identification of all wells whose depths have changed since their construction.
