1985: facility name was Innes Laundromat with a discharge to ut Mundy Creek, (zero 7010 and 30Q2). Model was run and

Settleable solids, 200 / 100 ml fecal coliform and 50 NTU Turbidity, (w/ language) for 0.015 mgd discharge. Second

1990: Region memo of numerous complaints from downstream residents of degradation to receiving waterbody. A to C had not
been issued for expansion from 0.015 to 0.075 mgd, therefore a in limits was recommended; BPJ limits of 15 mg/I BOD3, 4
mgA NH3N, 6 mg/l dissolved oxygen, 6 - 9 SU pH, 30 mg/l TSS, 6103 µg/I MBAS, 30 mg/l Oil & Grease, 200 / 100 ml fecal
coliform, 28 µo residual chlorine and 25 NTU Turbidity, (w/ language) for 0.075 mgd discharge. Model was run which included
this discharge as well as "Mom and Pops Western Steer" Restaurant.
1991: Requests for discharges of 0.015, 0.050, and 0.075 mgd were requested, (the limits are outlined below - note MBAS in mg/l).
Third -party administrative law hearing was called on issuance of this Permit. At issue was the flow statistics for this discharge.
Previous USGS flow statistics, (refer above) were deemed incorrect. During the hearing, Robert Mason (USGS) reported that
using the now existent Open -File Report 90-399, (what we now use) the flow statistics would be 0.74 cfs s7010 and 1.6 cfs
30Q2. Another model was run which deleted the "Mom and Pops Western Steer" Restaurant, (tied into Region plant) and
included the Cross Country Campground, (which had received a new NH3N limit) under these lower flow statistics. With the
previously recommended BPJ limits, dissolved oxygen was predicted to be protected.

1975 - 1976: many effluent limits sheets, most recommending various Advanced Secondary limits. One had models run for various
discharges, (I assume this facility was still in the planning stage).
1981: Two WLA's for discharges of 0.025 and 0.065 mgd. Both recommendations were for Secondary limits.
1986: remodeled w/ Secondary limits recommended. Note on WLA indicated that upon renewal, limits would be more stringent due
to interaction w/ Innes Laundromat discharge.
1991: remodeled accounting for other dischargers in area, [Killians Crossroads, NC0063355 approximately 3/4 downstream at
mouth). Region requested BPJ limits for lake dischargers, (15 / 4) be implemented; TSB did not have justification for such a
change, but NH3N limits were added due to ammonia toxicity, (facility chose that over toxicity test). Also, instream monitoring
was added.
