11. Performance
❑ 12 month performance
• We pumped the septic tank in August before school started back. Our
Dissolved Oxygen and Ammonia Nitrogen problems from last spring
continued when school started back in the fall. The problems finally
cleared up the last month before connection to the municipal sewer line
was made. (See "Corrective Measures Taken" section of this report for
more details)
• The sewer line connection date was extended several times due to, rain,
power lines not ready, and remote monitoring not ready. We kept thinking
that connection was only weeks away throughout the summer and fall.
Connection to municipal sewer was made on the afternoon of
December 1st 2003!
❑ Violations
Our permit requires us to monitor the water that we discharge from the system
and sets limits for each parameter that is monitored to ensure that the water is
safe for the environment. We monitor the following parameters weekly:
(Flow, Temperature, Dissolved Oxygen, Conductivity, and Residual Chlorine)
We monitor the following parameters BI-monthly:
(Biochemical Oxygen Demand, Ammonia Nitrogen, Total Suspended Residue,
Fecal Coliform, and pH)
Violations of the permit limits can result in civil penalties of up to $25,000 per day
per violation.
Permit Limit Violations:
August 2003- Dissolved Oxygen Daily Minimum Limit Violation
(Test Result = 4.93 mg/l, Daily Minimum Limit = 6 mg/1)
August 2003- Dissolved Oxygen Daily Minimum Limit Violation
(Test Result = 4.77 mg/I, Daily Minimum Limit = 6 mg/1)
September 2003- Dissolved Oxygen Daily Minimum Limit Violation
(Test Result = 5.77 mg/l, Daily Minimum Limit = 6 mg/1)
September 2003- Dissolved Oxygen Daily Minimum Limit Violation
(Test Result = 4.82 mg/I, Daily Minimum Limit = 6 mg/1)
September 2003- Dissolved Oxygen Daily Minimum Limit Violation
(Test Result = 5.77 mg/l, Daily Minimum Limit = 6 mg/1)
September 2003- Dissolved Oxygen Daily Minimum Limit Violation
(Test Result = 5.80 mg/I, Daily Minimum Limit = 6 mg/1)
September 2003- Dissolved Oxygen Daily Minimum Limit Violation
(Test Result = 5.77 mg/l, Daily Minimum Limit = 6 mg/1)
October 2003- Ammonia Nitrogen Monthly Average Limit Violation
(Monthly Average = 27.7 mg/l, Monthly Average Limit = 20 mg/1)

There have been NO monitoring and reporting violations during the last
year.
There has been NO (illegal) bypass of treatment facilities in the last year.
There have been NO sanitary, sewer overflows in the last year.
❑ Environmental impact of violations
• Effluent discharges into an unnamed tributary to West Belews Creek
Which is classified Class C waters in the Roanoke River Basin.
(Class C, is a classification that designates waters as "protected for
secondary recreation, fishing, wildlife, fish and aquatic life propagation and
survival, agriculture, etc. Secondary recreation includes wading, boating,
and other uses involving human body contact with the water where such
activities take place in an infrequent, unorganized, or incidental manner."
• Ammonia Nitrogen in streams and ponds at high levels can directly harm
fish. It can also cause oxygen depletion due to stimulating algae growth,
which harms fish and other aquatic life.
• Low oxygen in the water that we discharge will lower the oxygen levels in
the creek and could harm fish and other aquatic life.
1 haven't noticed any visible environmental changes in the creek resulting
from these violations. Rain has probably helped us by keeping the creek
flushed out and the wastewater diluted. The creek should definitely get
healthier since we've tied into the city sewer.
❑ Corrective measures taken
Dissolved Oxygen Problem: Old sand in the sandfilter was likely the cause
of the oxygen problems that we had in August and September. Sand
wasn't replaced with new over the summer due to the expense and the
fact that the sewer line was to be completed before school started back.
The sewer line wasn't completed on time. We kept thinking that the
connection was only weeks away throughout the summer and fall. I
continued working with the sand by keeping the surface clean, diverting
water to better draining areas, and adding new sand to low areas until we
finally started getting better oxygen results. It took over a month to finally
get things right, but I knew that this would only last for a little while and
had to keep working with the sand to keep oxygen readings within limits.
Ammonia Nitrogen Problem: Upon getting the oxygen problem solved, we
started having ammonia nitrogen test problems. I feel that the old sand in
the sandfilter caused this problem also. I knew that without replacing all of
the sand it would be hard to keep our tests within limits. By continuing my
work with the sandfilter, I was surprised and pleased to be able to get the
ammonia nitrogen back within limits for the month of November.

IV. Certification
Tougher restrictions and penalties concerning discharges into our surface
waters has helped to improve water quality all over the state. Years ago, many
businesses were forced to upgrade their wastewater treatment facilities, or
discontinue their use and cease discharge to meet water quality standards. Both
Walkertown schools wastewater systems were old, and designed to meet less
strict water quality standards. They couldn't meet the new permit requirements
without being upgraded. The NC Department of Environment and Natural
Resources agreed, in an (SOC) which extended our permit limits, to let us
continue to operate the systems without upgrades until the town of Walkertown
could get it's public sewer system operating. The result of this is that the school
system was able to contribute money to Walkertown to help build the new sewer
system, rather than spend the money upgrading the old facilities.
We had some problems meeting our SOC limits this year. I wanted to be able to
continue meeting our permit requirements until the school was tied to the new
sewer line. With the old contaminated sand in the sandfilter this didn't happen. I
was happy to be able to get back in compliance for the month of November. I
was even happier when we tied into the new sewer line on the afternoon of
December Vt. Following connection to the sewer line, remediation of the site
began. The septic tank was pumped down and backwashed. Walls, fences,
pipes, and other structures were demolished and hauled away. The tank was
crushed in and filled with gravel. Then everything was covered over with dirt to
bring up to surrounding grade level. The areas were then seeded and covered
with straw. We have sent in a request to have our permits for these facilities
rescinded. I have returned to the site several times and have been pleased to
see clear water running in the creek.
The'creek behind the Walkertown Schools runs into West Belews Creek. Fish
and other wildlife use the water that drains from, and runs across our grounds,
and people use it for recreational activities. I am happy to see the new sewer
system in operation. It will certainly provide a healthier environment for everyone!

Subject: Permits remission request for Walkertown Schools
The Winston-Salem Forsyth County Schools is requesting remission of all
permits related to the operation of our wastewater treatment plants that have
served Walkertown Elementary School and Walkertown Middle School.
Permits included in remission request:
NCO035602 (Walkertown Elementary School)
NCO036599 (Walkertown Middle School)
EMC SOC WQ 91-37 Ad III (Both Walkertown Schools)
On December 1st, 2003 the connection lines to both of our treatment plants were
severed and plugged. Both Walkertown schools were connected to the Town of
Walkertown's Municipal Sewer System. There will be no further discharge from
our treatment plants. We are in the process of demolishing the treatment plants.
(Including: disposal of tank contents and plant structures, and remediation of the
site according to regulations) We expect to be finished with demolition by next
week..
