Accelerated Monitorine Status:
The EFR February 9,2015 submission requests that the ,fbllowing wells/parameters be returned to baseline
monitoring frequency:
o MW-1/Tetrahydrofurano MW-23ffield pH
The request is based on the most recent laboratory resultr; for these wells/parameters showing results less
than the Ground Water Compliance Limits (GWCLs) lisred in the Permit. The Division's review of the
laboratory results verified that the requested wells/paranreters showed eight consecutive monthly laboratory
results below the GWCLs.
Based on this review, the following wells/parameters are, authorized to be returned to baseline monitoring
frequency as follows:
Monitorins Well Parameter Baseline Monitorine Freouencv

EFR agrees to submit a Source Assessment Report (SAR) for the above listed constituents in monitoring
well MW-31 to the Director within 90 days after approv:rl of the EFR Plan, which will follow the format of
