~ RE: Aggregate MiM ng Operation ~ ~~
2 Mi les W. Jct. U.S. 6 and X40 .~ ., ,
Dear Mr. Case:
We wish to confirm the details of a visit made ty Messrs.
~ , Gary Polvi of the Environmental Protection Agency and Richard Bowman ~
of Colorado Department of Health, Water Quality Control Division, i:o
your aggregate mining operation located approximately three (3) miles ~~.
south of the city center in Golden, Colorado. This visit was made
on ilovember 7, 1973, at which time Messrs. Polvi and Bowman met with q~,v '•.W
~• ~. you to discuss the question of whether an NPDES wastewater discharge ~'~"
peefait is requircd for this operation. I~•' ..
« A tour of this aggregate mining operation by the above parties:
disclosed that there are presently no process generated wastewater:. ~~`
enAnating from the facility. Storm runoff and spring thaw waters ~~
' which enter the mining site are diverted through a french drain tY{~e ..
of runoff control system to control process contamination. -..,..
Based on the findings of Messrs. Polvi and Bowman, the ~'
Environmental Protection Agency believes that this aggregate minim{
operation presently complies with all Federal and State water ;,~.
pollution control requirements. Since there is presently no direct
•' discharge of process wastewater or contaminated runoff from the site, ;
and to long as the operating conditions at the faci 1 i ty r•emai n %;,, '~.,~;
unchanged, a permit to discharge liquid effluents is not required. •
