RE: Docket No. D-8451 - Groundwater Recovery Report

Dear Mr. Everett:

Please find enclosed a revised quarterly Groundwater Recovery Report submitted inaccordance with the conditions set forth in Docket No.~D-8451, for the period April 1 throughJune.30, 1993. : .

The report has been revised in response to the attached letter submitted by Standard Chlorineof Delaware, Inc. (SCD) to the Department of Natural Resources and Environmental Control(DNREC) and subsequent discussions. As you will note, the Quarterly Report has beenabbreviated to include only a summary of water withdrawal rates, water table elevations,results of analysis and recovery well operation. The DNREC is further evaluating a requestto reduce the frequency of collection and number of wells designated for sample analysis. Anannual report will continue to be prepared in a manner consistent with past reports and will besubmitted following the first calender quarter.

Feel free to contact me should there be any questions.

Very truly yours,

Paul JohnstofManager, Environmental

RE: Groundwater Monitoring Report _

Dear Ms. Hiller:

Per our recent discussion and in accordance with the conditions of Section I, Paragraph 6 ofthe Consent Order between Standard Chlorine of Delaware, Inc. (SCD) and the DelawareDepartment of Natural Resources and Environmental Control (DNREC), SCD requests areduction to annual submission of groundwater monitoring reports. The annual report will beprepared in a manner consistent with past reports and meeting all requirements of the ConsentOrder.

In addition, SCD proposes to continue to provide an abbreviated quarterly report documentingwater withdrawal rates, groundwater elevations for all currently monitored wells and samplingresults for wells TW-I, TW-2, TW-3, TW-4 TW-22, TW-24, RW-1, RW-2, RW-3, RW-4,and RW-5. It is expected that submission of mis data will provide the DNREC with adequateinformation to evaluate the general performance of the recovery system and monitor anypotential for migration of the contaminants in an east, west, or south direction. As you areaware, although the concentration of contaminants has been reduced, their relative distributionwithin the plume has remained stagnant Therefore, further monitoring of wells within theplume is not expected to provide significant new information.

Finally, SCD requests that the requirement for signature by a registered professional geologistbe waived for all reports or, at a minimum, for the proposed quarterly reports. Should theDNREC concur with this request, SCD proposes that the revised reporting commenceimmediately and that annual reports be submitted on the anniversary of the first quarter 1993report

Your promprfisview and decision on this request is greatly appreciated. Feel free to callshould you have any further questions.

Very truly yours,

Paul JohnstonManager. Environmental
