Dear Ms. Coriale:
In response to your telephone request, I have attached a tabulation
of the effluent limits for the proposed Holly Springs WWTP--site 3. The
limits are maximum monthly mean values unless otherwise noted. The limits
reflect the current policies and methodologies of the State Continuing
Planning Process. A brief explanation of these policies is also attached.
Please feel free to call me if you have any questions concerning these
limits.

DISCUSSION OF EFFLUENT LIMITATIONS
Effluent limitations for BOD5, NH3-N, and dissolved oxygen are established in
the State Water Quality Management Planning Process to attain water quality stream
standards for dissolved oxygen. The limits for BOD and NH3-N are usually specified
as maximum monthly mean values. Maximum weekly values, normally 1.5 times the monthly
value:;, are also specified in the affected discharge permits.
There are two basic levels of analysis ("B" and "C") used to establish the
effluent limits. In each case the analysis can conclude an infinite nun.ber of
combinations of effluent BOD5, NH3-N, and D.O. that will attain water quality
standards. Obviously it would be impossible to list all combinations ani since
spee_f is values must be in the NPDES permits, the Division staff selects a likely
combitation for specification of the waste load allocation. Because of the numerous
combinations which can be conceived, it is possible that some combinatior other than
the one selected by the Division of Environmental Management (DEM) will prove to be
the optimum. For this reason, DEM encourages the consideration of alternative
combinations in the 201 Planning Process which may be advantageous due to the
particular waste or waste treatment being considered. Since the waste load
allocations and often the NPDES permits precede the development of 201 plans, it
will be necessary to update plans and modify permits in a continuing process.
The "B" and "C" levels of analysis differ primarily by the amount of data
available. The "C" analysis is based on intensive water quality survey data while
the "B" analysis is an empirical analysis based largely on the slope and other
physical characteristics of the receiving stream. Additional explanation of the
"B" and "C" analyses is contained in Appendix E of the Basin Plans. Both analyses
use the basic Streeter -Phelps theory. In a "B" level analysis effluent ultimate
BOD (BODu) is set equal to BOD5 + 4 x NH3-N. The combination of BOD5 and NH3-N may
be modified as long as BODu is not changed. In most level "C" analyses Carbonaceous
BODu (CBOD) is equal to 1.5 x BOD5 and Nitrogenous BODu (NBOD) is equal to 4.5 x NH3-N.
Although tradeoffs between BOD5 and NH3-N are acceptable in the level "C" allocations,
the equation of BODu = 1.5 x BOD5 + 4.5 x NH3-N cannot be used in all cases. When a
large difference between Carbonaceous BOD and Nitrogenous BOD stream removal rates
exist, the trade-offs will be less in accordance with the equation. In any case,
modifications to the waste load allocations have to be approved by DEM before 201
plans or NPDES permits are completed. Proposed allocation modifications should be
coordinated through the Local Programs or Technical Services Sections.
As a result of regulation changes, the effluenc limits on suspended solids may
be increased from the normal 30 mg/1 to 90 mg/1 for lagoon waste treatment systems.
Since the attached table does not address the type of treatment system to be employed,
this consideration should be utilized in the design of the waste treatment system.
Even though higher suspended solids are allowable for lagoon systems, the systems
must be designed to allow attainment of the BOD, NH3-N, and D.O. effluent limits.

Additional Explanation:
Five potential discharge locations have been reviewed by the modeling
group for the Town of Holly Springs. Three of the sites are located along
Little Branch and the other two sites are located at the headwaters of Utley
Creek (map attached) . In each case, the U.S.G.S. has estimated a 7Q10
of 0.0 cfs for the entire stream segment during summer and winter conditions.
Therefore, assimilative capacity will be heavily influenced by stream reach
characteristics such as slope, length, and average flow conditions (which
are primarily responsible for the shape of the Channel). In this manner,
greater assimilative capacity during low flow conditions will exist for
discharges located at the headwater portions of the stream.
However, since the headwater locations are essentially dry ditches,
there may be a greater potential for nuisance conditions to arise at these
sites. This will largely depend on the amount and quality of wasteflow
from the proposed Holly Springs facility. In general, the large flows,
ultimately expected (i.e. 250,000 gpd) should prevent nuisance conditions
from occurring since "pooling" should not be a problem.
Site 4A may be of particular interest as a potential site of waste
disposal. This location lies directly below the springs from which the
town draws its name. It is likely that the springs feed Utley Creek year-
round. However, the U.S.G.S. does not gage this stream nor do their
empirical dquations amount for the presence of the springs. The allocation
for this site, therefore, was completed assuming a 70_0 of 0.0 cfs.
Nonetheless, some dilution of wasteflow during low flow conditions might
occur because of spring -fed waters.

Dear Mr. Westall:
Please refer to our recent conversations with you and
your staff concerning the establishment of effluent limits
for alternative wastewater treatment facility sites for the
Town of Holly Springs. We would like to request, on behalf
of the Town of Holly Springs, a determination of the effluent
limits at the locations noted on the enclosed map for design
flows of 0.25, 0.3 and 0.4 mgd.
In addition, we would appreciate your indication as to
whether or not the effluent limits provided with your letter
of April 7, 1976 to Moore, Gardner and Associate, Inc. for
effluent discharges at SR 1301 and SR 1006 on Middle Creek
remain valid. If not, we would appreciate revised effluent
limits for these sites.
If you have any questions or require additional informa-
tion, please feel free to contact me.
Yours sincerely,
HAVEN AND1SAWYER, P.C.
