Dear Mr. Stovall:
Enclosed you will find a copy of the Compliance Biomonitoring Inspection
report for the inspection conducted the week of October 23, 2000. The inspection
included the same objectives as that of a routine Compliance Evaluation Inspection
(conducted on October 24, 2000) plus an Aquatic Toxicity (AT) test to evaluate the
biological effect of the facility's discharge on test organisms. As part of the inspection a
tour of the Wastewater Treatment Plant was conducted. All observations and
recommendations are in Part D. Summary of Findings/Comments of this inspection
report. A 24-hour Plant Outfall 001 effluent composite sample was collected on October
24 and 27 by Dale Lopez (DWQ) and split with Tritest, Inc. for use in a chronic
Ceriodaphnia dubia pass/fail toxicity test. The aquatic toxicity analysis was completed
by the Division of Water Quality Aquatic Toxicology Laboratory, located on Reedy
Creek Road in Raleigh. The pass/fail toxicity test, using these samples, resulted in a
Pass; and, it indicates that the effluent would not be predicted to have water quality
impacts on receiving water. Additionally, 24-hour composite samples were taken for the
five-day BOD test, total suspended solids, ammonia as nitrogen, total Kjeldahl nitrogen
as nitrogen, nitrate- and nitrite as nitrogen; and total phosphorus. The results of these
parameters will be forwarded to you when they are completed by the Division of Water
Quality Chemistry Laboratory, located on Reedy Creek Road in Raleigh.
If you have any questions or comments concerning this report or require
clarification on part(s) of this report, please feel free to contact me at 910/486-1541.

McCain hospital Wastewater Treatment Plant (WWTP1
BIOMONITORING EVALUTATION INSPECTION performed during the week of
October 23, 2000
Contact personnel:
Darrell Cockman (ORC)
J.A. Bolton (Back-up ORC)
DESCRIPTION OF McCAIN WWTP:
McCain WWTP has a total average flow of 140,000 GPD. Flow comes from the
prison, the prison hospital, and the youth facility (1200 population); food services,
laundry (Hoke Correction - Medical security), larger laundry is from -Sand Hill Youth
Correctional, one lift station (East side), two bathrooms, and backwash from the water
treatment plant. Flow travels through either the manual barscreen or the Lakeside
automatic bar screen, then into a 300,000 gallon capacity Aeration Zone (93 feet in
diameter by 6 feet deep, with three each 10 HP surface aerators (detention time of
approximately 48 hours). Wastewater flow then travels to a Flow Splitter Box (which
can run clarifiers in series, in parallel, or isolate either of the two clarifiers (for example,
when maintenance is performed every six months on each clarifier). For normal
operation, flow travels to Clarifier #1 (31 feet in diameter by 13 feet deep), then to
Clarifier #2 (the polishing clarifier, whose dimensions are 31 feet by 6Y2 feet deep).
Flow then travels to the disinfection unit, with UV lights (Trojan UV 3000B — with a
total of 20 bulbs). After disinfecting, the flow travels through the Parshall Flume with a
Sigma Ultrasonic flow meter, to Mountain Creek, and finally to the Lumber River.
Concerning the Return Activated Sludge (RAS), the underflow from Clarifier #1 travels
through a Telescopic Valving Box, then through a 3-Way Valve, and finally back to the
Aeration Zone. The 3-Way Valve can also be switched so that the underflow travels to
the Aerobic Digester (with 2 each 15 HP submersible aerators) for wasting of sludge:
Waste Activated Sludge (WAS). The square Aerobic Digester's dimensions are 22 feet
by 20 feet by 40 feet deep, with a capacity of 99,000 gallons. WAS occurs an average of
three times per week at approximately 3,800 gallons each time. Scum from Clarifier #1
flows through a scum pump (with a manual switch), then to the Aerobic Digester.
Supernatant from thedigester travels back to the Aeration Zone (through a black ABS
hose). Digested sludge from the Aerobic Digester flows to six Drying Beds with a total
area of 7500 square feet, 1250 square feet of area for each bed (25 feet by 50 feet). From
the Drying Beds the dried digested sludge is taken to Land Application located next to
.the WWTP.

3. The SVI is now in the range of 180 to 220 mL/g. The preferred range, as stated
in Tony Arnold's Technical Assistance letter to McCain WWTP (November 23,
1999), is 25 to 100 mL/g.
4. The 30 minute settling test is approximately 700 fo 850 mL/L. The preferred
range is approximately 400 to 600 mL/30 minutes.
5. The MLSS'is approximately 3400 mg/L.
6. The Effluent 001 Discharger Monitoring Report (DMR) for May 2000 was
compared to the bench sheets for each parameter. All data results were in
agreement except that of the pH for May 31st. Instead of 7.2 pH units, it should
have been 7.3.

LABORATORY TOUR---
1. Parameters done on site: dissolved oxygen, conductivity, pH, and temperature.
2. Parameters done off -site (Chemical & Environmental Technology, located in
RTP, NC): fecal coliform, biochemical oxygen demand, ammonia, total nitrogen,
oil and grease, total phosphorus, total suspended solids, and aquatic toxicity (sent
from CET. to Tritest, Inc.).
3. Dissolved oxygen is performed with a YSI 51B meter, and calibrated on moist
air.
4. Temperature is performed with a Fischer Scientific NIST traceable thermometer
S/N 1257 (CAT #: 5043B), which has a range of —1 to 101 degrees Centigrade.
5. A Fischer Scientific Model 955 pH meter is sloped daily using aliquots of pH 10
and pH 4 buffers, and checked with a pH 7 buffer. The aliquots of pH buffers
are changed every six weeks.
6. Fischer Scientific pH buffer expiration date checks:
Buffer
Date
PH4
December 2001
pH 10
December 2001
pH 7
December 2001
7. Conductivity is performed on a Fischer Scientific Digital Conductivity Meter.
It is calibrated using a 100.7 micromhos standard (expiration date of 12/06/00).

RECOMMENDATIONS---
1. Recommend that, in order to calculate the % error, the calibrations report sheet of
the Sigma Ultrasonic flowmeter have the ultrasonic's reading before . and after
calibration, and the Parshall Flume head measurement (in inches at the ultrasonic
flowmeter location). According to 15A NCAC 2B .0505 (b)(1): "Devices
selected shall be capable of measuring flows with a maximum deviation of less
than 10 percent from true discharge volumes. Flow measurement devices shall
be accurately calibrated at a minimum of once per year and maintained to ensure
that the accuracy of the measurements is consistent with the accepted capability
of that type of device."
2 Please submit an amended Discharger Monitoring Report for the pH error on
May 3, 2000. This request is in accordance to McCaiir's NPDES permit, Part II,
Section E; (8): "Where the permittee becomes aware that it ... submitted
incorrect information ... -in any report to the Director, it shall promptly submit
such facts or information." The following procedure should be followed in
submitting the corrected report:
A. The corrected data should be written in red ink or hi -lighted.
B. At the top of the Effluent Page, the words "Corrected Report" or ,
"Amended Report" should be written in red ink on all copies. This will
differentiate between the originally submitted report and the corrected
report.
C. Two (2) copies of the corrected report should be submitted to this
Division and one (1) copy must be retained by the permittee.
D. A brief explanation for the correction should be written either on the
backside of the Effluent page or in a cover letter accompanying, the
reports.
