Carson ( DENR - WATER QUALITY COURCF RagryDN Dear Sir, I am writing this letter on the behalf of the following Permits numbers. NCO055271 Shields Mobile Home Park NCO042528 B. Everett Jordan I am the contract ORC for both of the plants. At both plants, we wish to change over to UV. I am having a problem is trying to find an Engineering company who can do this for us. Most of the ones I have contacted wanted way too much money and as small as we are we can't afford the cost on this. I have found one who is willing to do the project for us; the only thing is we are running out of time. To keep cost down for us he works on it when he has a break and it has taken longer than normal. To have the request to construct permit to go through, I was told it could take up to 90 days for the state to go over it for approval. The permit number NCO055271 has to meet the new CL2 rule Dec I". Permit number NCO042528 has until Feb Ist. Furthermore equipment to read low CL2 in the field is much more expensive than the cost of the UV, with having to install D-CL2 and having to feed tablets for CL2 and D-C12. even several of the engineering companies would not even talk to us due to it was not enough money for them to work on it. I would like to request an extension on the permits to allow time to be approved by state and install the equipment. I know we had 18 months to get this in order but, I had to find a company who could work with us on this matter. Our engineer should have the plans and request to construct completed within the next 2 weeks and hope to turn it into the state for approval then. Thank you for your time on this matter, we hope you can help us out on this. Si erely, le , ��, James M. Carson
