NPDES Permitting Guidance
NPDES Implementation of Ammonia Criteria- Update
secrelaly
S. JAY ZIMMERMAN
Director
NC has still not adopted an ammonia standard, though it is on our WQS Triennial List for next
round. NC did establish ammonia chronic criteria for use in NPDES permitting back in 1989/90,
which was based on EPA's 1986 criteria development document that factored in pH/Temp across
three regions of the State (see attached). This evaluation resulted in ammonia chronic criteria of
1.0 mg/l NH3-N (summer) and 1.8 mg/l NH3-N (winter) for use in permitting purposes. NC
implements these chronic criteria as Monthly Averages limits utilizing instream dilution. In
2002, NC developed procedures for complimentary acute permit limits (discussed below).
The current ammonia permitting procedures should be as follows:
• The NH3/TRC Wasteload Allocation (WLA) spreadsheet automatically calculates
appropriate ammonia Monthly Average limits for summer and winter. The spreadsheet
assumes a background ammonia concentration of 0.22 mg/1.
• For any permit (new/renewal), always run the NH3/TRC WLA spreadsheet to verify
appropriate Monthly Average Ammonia Limits for protection of aquatic life.
• If the allowable ammonia concentration is greater than 35 mg/l, no limit should be
imposed.
• If the allowable concentration is less than 35 mg/l, then the allowable limit is needed and
the spreadsheet will automatically calculate it.
• For Municipal facilities, the acute limit will be expressed as a Weekly Average, and is
based on multiplying the Monthly Average limit by a factor of 3.
• For non -Municipal facilities, the acute limit will be expressed as a Daily Maximum, and
is based on multiplying the Monthly Average limit by a factor of 5.
• If a new more stringent ammonia limit is required, discuss the need for a Compliance
Schedule with senior staff and then with the Permittee.
• There is no RPA procedure used for ammonia; it is implemented strictly based on WLA
spreadsheet results (similar to TRC).

• A sample NH3/TRC WLA is attached. In this example, the spreadsheet indicates that
Monthly Average ammonia limits of 3.2 mg/1 and 12.7 mg/1 should be imposed for
summer and winter, respectively, in order to protect for NC's chronic ammonia criteria.
Some additional considerations:
This guidance will need to be revisited after NC formally adopts an ammonia standard for
both chronic and acute aquatic life protection.
In the past, some ammonia limits were based strictly on protection of our DO standard
rather than ammonia toxicity, and that is why the permit writer should always verify the
correct ammonia limit with any permit renewal using the WLA spreadsheet.
In the past, some practices allowed for maintaining a less stringent ammonia limit if the
facility was consistently passing the WET test (i.e., biology trumps chemistry). This is
no longer a valid approach and EPA would object. In April 2016 EPA expressly stated
that NC cannot use biology to override chemical results. EPA also disallowed the use of
Action Levels in permitting, in which toxicity test results (if passing) were used to
override the need for permit limits for copper/zinc/silver/iron/chloride.

FROM: David A. Goodrich
NPDES Unit Supervisor
SUBJECT: Total Residual Chlorine Policy for NPDES permits
Every three years the State is required by the Clean Water Act to review its surface water quality standards and
classifications, determine if changes are needed and to make any necessary changes. This review process is referred to
as the "triennial review." Public hearings were held to solicit comments for the 2000-2003 Triennial Review of surface
water quality standards during the summer of 2002. The Hearing Officer's recommendations were presented before
the state's Environmental Management Commission on October 10, 2002.
The Hearing Officer's recommended changes included modifications to the existing standards for Arsenic, Cyanide,
Methylene Blue Active Substances (MBAS) and Total Residual Chlorine (TRC). The Hearing Officer also
recommended the addition of a standard for Methyl Tert-Butyl Ether (MTBE).
All of the Hearing Officer's proposed changes were adopted with the exception of MTBE. The changes took effect
on April 1, 2003. This memo documents the changes to the NPDES permitting policy for TRC limits.
Total Residual Chlorine (TRC)
Previously, TRC had an Action Level Standard, except in designated Trout waters. The Triennial Review changes
modified the TRC Action Level Standard to an Aquatic Life Standard of 17 µg/L. The Aquatic Life Standard will
remain for designated Trout waters.
Aquatic Life Standard — 17 µg/L (freshwater only) Trout Waters — 17 µg/L
Revised TRC Policy
➢ TRC limits will be assigned to permit renewals and all new permits issued after April 1, 2003.
➢ Facilities that do not use chlorine will not receive a TRC limit; however, the presence of a chlorine back-up
system to augment UV or other disinfection requires a TRC limit.
➢ Facilities discharging to streams with a 7Q10 <0.05 cfs (zero -flow streams) will receive a limit of 17 µg/L.
➢ Limits will be capped at 28 µg/L to protect against acute impacts.
It is likely that many facilities will need to add dechlorination (or use another means of disinfection) to comply with
the new TRC standard. Therefore, a compliance schedule of 18 months from the effective date of the permit may
be added to any TRC limit added during the current permit renewal. This time period is allowed in order for the
facility to budget and design/construct the dechlorination and/or alternative disinfection system(s). The NPDES
Unit has promulgated minimum design criteria in order to expedite permitting of dechlorination equipment.

Subject: Draft NPDES Permit NCO046418
Mountain View Elementary School WWTP
Grade I Biological WPCS
Wilkes County
The Division has reviewed your request to renew the subject permit. Please review this draft carefully to ensure a
thorough understanding of the information, conditions, and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
• Section A. (3.) has been updated to require electronic submission of
effluent data reports (DMRs). Federal regulations require electronic
submittal of all discharge monitoring.
• An updated outfall map has been included.
• In July 2016 the NPDES program began implementation of revised ammonia
criteria based upon the potential for toxic impacts from ammonia [see
attached memorandum]. As permits are received for renewal (or major
modification), ammonia limits will be calculated as per the 2016 memo and
implemented. The ammonia limits will take effect in 2028 to allow your
facility time to make any necessary modifications to meet the limits.
• Total Residual Chlorine limit has been updated because streamflow
conditions require a limit of 17 µg/L, this new limit will take effect in 2028.
The NPDES standard conditions (Parts II, III, and IV) that are a part of the permit are not included in this draft
document (cover, map, and Part I). The conditions are the same as in your current permit except that agency and
division names have been updated. The latest version is available at ht1ps://bit.ly/3k5NFaL and can be viewed
online or downloaded as a PDF file.
With this notification, the Division will solicit public comment on this draft permit by publishing a notice in
newspapers having circulation in the general Wilkes County area, per EPA requirements. Please provide your
comments, if any, to me at the address below no later than 30 days after receiving this draft permit.
Following the 30-day public comment period, the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit. If you have questions concerning the draft, please contact me at
[phone] or via e-mail at kate.shadwell&deq.nc.gov.
