a. Classification: C
b. River Basin and Subbasin No.: Yadkin -Pee Dee 03-07-06
c. Describe receiving stream features and pertinent downstream uses: From the boiler
blow down pond, the discharge enters a wet -weather ditch that travels for a distance
of several hundred feet before it enters the UT. The receiving stream appears to be an
intermittent stream and is noted as such on the USGS topo map. Downstream uses
are typical for class C waters.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of wastewater to be permitted: The applicant has estimated a maximum
flow of 500 GPD of boiler blow down wastewater.
b. What is the current permitted capacity of the wastewater treatment facility? There is
no current capacity.
c. Actual treatment capacity of the current facility (current design capacity)? unknown
d. Date(s) and construction activities allowed by previous Authorizations to Construct
issued in the previous two years: This facility has not been issued an ATC in the past
two years.
e. Please provide a description of existing or substantially constructed wastewater
treatment facilities: The existing WWT facilities consist of a small, settling
(detention) pond for temperature control with pH adjustment prior to discharge. The
settling pond provides up to six days of storage.
f. Please provide a description of proposed wastewater treatment facilities: There are no
WWT facilities being proposed at this time.
g•
Possible toxic impacts to surface waters: The applicant indicates that only sulfuric
acid is added to the waste stream.
