Re: SOC'#EMC-WQ-81-43
Granite Falls, North -Carolina
'As you may know, the Town of-Cranite'Falls-received both EPA and
State Clean Water Bond Grants in July, 1984, to aid in financing the
upgrading and expansion of our wastewater treatment plant. In December,.
1984, we completed the preparation of_plans and specifications and are
now awaiting approval to advertise the project for bids.
The Town is currently operating the treatment plant under the provisions
of'SOC #EMC-WQ-81-43. The SOC was originally issued in 1981 as we
anticipated EPA (and State funding) for FY 82-83. As we have explained
in previous correspondence, there was a mistake in our priority rating
which delayed our funding -for two (2) years. As noted above, the Town
has secured the necessary grant funding and we have committed monies
from our reserves to cover the local share of the project.
During this interim period while plans for the treatment plant
improvements project were being designed, the Town was fortunate to
have a roost desirable industry locate in Granite Falls and we need to
supply the industry with water and sewer service. Accordingly, the
Town -of Granite Falls wishes to :amend --its_.current ::SGC _by_ ,(1) revising
the irrplemntation schedule to coincide with the schedule set forth
in our EPA grant agreement and (2) requesting additional wastewater flow
be allowed to discharge to'our collection system for treatment and dispoeal.
In support of this request, you will find attached hereto a resolution
by the Town indicating its commi.tnent to meeting the required effluent
limits, regardless'of the availability of funding from other sources.
Further, we propose -the following schedule be.included in the revised
SOC for completing contruction of the project.
MAR 2 ? 199

` Mr. R. Paul Wilms
Page 2
March 15, 1985
1. The project will be advertised and bids received on cr
before July 1, 1985.
2. Construction will begin on or before September 30, 1985.
3. Construction will be completed on or before November ,30, 1986.
4. Plant will attain full compliance with effluent limits by
February 28,1987.
Lastly, we havelisted below the wastewater flows (and sources)
anticipated within the above implementation period.
1. NEPTCO (New Industry); sanitary waste only. Initial 100
employees @ 30gpcd _ 3,000gpd.
2. Restaurant on Hwy. 321 (existing) = 2,000gpd.
3. NEPTCO (Additional - within 3 years); sanitary waste only.
200 employees @ 30gpcd = 6,0 Ogpd.
4. Residential growth on undeveloped lots with -existing service;
30 dwelling units @ 300gpd%unit = 9,O00gpd.
5. Sanitary waste from Commercial/Light Industrial site currently
being developed on Hwy. 321. 100 employees @ 30gpcd = 3,000 gpd,
TOTAL'FLOW ALLOWANCE REQUESTED = 23,000gpd.
.In making this request., we understand the interim effluent limits
cited -in the SOC (BODS = 40 mg/l-and TSS = 45 mg/1) will remain unchanged.
Should you have further questions.regarding this matter, please
contact Mrs. Linda K. Story, Town Manager or Mr. Arthur L. Kennedy,
with L.E. Wooten and Company, who are consulting engineers for the Town.
Thank you for your continued interest in our project and your consideration
of the request for a revised SOC,._
