Box 653 <br />Nederland, Colorado 80466 <br />RE: Delinquent Discharge Monitoring Reports <br />CDPS No.: CO-0032751 <br />Boulder County <br />Dear Mr. Hendricks: <br />~ -~(L~IINNII'Ir~~~r~~ir O <br />OF' Cpl <br />,~ .~ <br />~~. <br />« rB]6 <br />MAY Q 6 1993 <br />DivlSlon Uf Mine131y n ve~~.;~y <br />Roy Romer <br />Governor <br />Pavica A. Nolan, MD, MPH <br />GecuVVC Dirmor <br />[ have reviewed the list of delinquent Discharge Monitoring Reports per your phone call of April <br />27, 1993. ~As we discussed on the phone today, it appears that we were in error concerning <br />some of the item. <br />The letter of April 22, 1993 stated that we had not received a DMR for outfall 3001, Your <br />permit does not require influent monitoring be done. Outfall 3001 is the outfall indicator used <br />for influent monitoring. Therefore, you are not required to submit DMRs for this outfall. The <br />letter also stated we had not received DMRs for outfall 0801. This outfall covered the special <br />monitoring required in Part I.B.12 of the permit. The monitoring for hardness was to last one <br />year. It is not clear how long Flow monitoring was to take place, however it can be reasoned <br />that a year time period was intended. The Division first received data relative to this <br />requirement with the April 1991 DMR. Therefore, we currently have over a year's worth of <br />hardness data. Per our conversation, you stated that monitoring of the Flow was attempted but <br />because of winter conditions it was not possible to reach the weir and perform measurements. <br />It is my understanding that we will be receiving a written explanation of this in the near future. <br />Once this information is received we will also have a year's worth of flow data. Therefore, the <br />requirement to continue to perform flow and hardness monitoring is no longer required. We <br />would appreciate receiving data, however such submissions will be optional. The Division will <br />evaluate the flow and hardness information submitted so far. This may result in a modification <br />to the effluent limitations or a requirement to perform additional monitoring. In either case, the <br />permit will be amended and [he changes public noticed so that you will be able to comment on <br />them. <br />
