Re: Effluent Limitations
Town of Granite Falls
year Mr. Westall:
CONSULTING ENGINEERS
TELEPHONE [phone]
Reference is made to your September 20, 1983 letter to Mr. A.W. Huffman
Jr., Mayor, Town of Granite Falls concerning the effluent limitations
for the Granite Falls Wastewater treatment plant. The'effluent
limitations were issued .for two different design flows - 0.5 mgd and
0.'865 mgd. However, based upon the revisions in the 201 Plan, the
design flow for the Granite Falls Wastewater'Treatment Plant is 0.750' mgd.
Accordingly, we will appreciate your providing us the effluent
limitations for 0.750 mgd design flow.
Thank you for your assistance in this matter.
Sincerely,
L.E. WOOTEN AND COMPANY
