Aggregate Industries - WCR Inc. <br />Amendment No.l - Jeronimus Property <br />Permit # M-1999-034 <br />We now believe that time is of the essence, and request a speedy response from the Division <br />regarding the issues and concerns we raised nearly one yeaz ago. A comparative understanding <br />of water quality data requires the collection of baseline data prior to implementing an action that <br />may influence the data. The U.S. Environmental Protection Agency, Region VIII, have <br />produced a number of standard operating procedures for field sampling activities. These include <br />minimum requirements for field sampling activities, requirements for quality assurance plans, <br />standard operating procedures for surface water sampling, standard operating procedures for <br />ground water sampling, and sampling equipment decontamination procedures, among others. <br />We believe these guidance documents would provide an excellent basis for evaluation of any <br />monitoring plan submitted by the operator and a means to assess the validity of any water <br />samples already collected. <br />We look forwazd to the Division's timely response on this matter, and are happy to provide any <br />t5u~cuher information that may_of assistarice'_tio~6lh~. <br />Sincerely, ~ ~ e n <br />4 /COY ~^~ <br />Karen & Ralf Topper <br />enclosure <br />2 <br />
