Dear Permitting Unit:
The Town of Denton is submitting the renewal application package for NPDES permit

- Section 4: Industrial Discharges
o Table F
- Section 6: Checklist and certification Statement
- One copy of Permit Renewal Package
The Town has the following comments regarding the NPDES permit:
- We are requesting the daily effluent monitoring of temperature be removed from the permit
or that the monitoring be reduced. There are no operational aspects that can influence the
temperature of the discharge.
- We are requesting that Dichlorobromomethane be removed from the permit. EPA Rule
391-3-6.03 (5)(e)(iv) states that the in stream concentration for Dichlorobromomethane
shall not exceed 17 ug/L under average or higher flow conditions. Based on the historical
monitoring of this parameter, the effluent concentration would not cause exceedance of
this standard.
- We are requesting that Bis(2-Ethylhexyl)Phthalate be removed from the permit. Fifteen of
the sixteen samples analyzed for Bis(2-Ethylhexyl) Phthalate were below the detection
level.
- We are requesting reduced monitoring as an"exceptionally performing facility"for BOD5,
Ammonia Nitrogen, Fecal Coliform and Total Suspended Solids (TSS). A review and
analysis of testing results for the past three years:
Percent of Monthly Average Limit
Parameter Most Restrictive 3-Year Average % of Limit
Monthly Limit
BOD5 April 1 —Oct 31 5.0 mg/L 2.29 mg/L 46%
BOD5 Nov 1—Mar 31 10 mg/L 4.33 mg/L 43 %
TSS 30.0 mg/L 5.37 mg/L 18%
Ammonia N 2.0 mg/L 0.057 mg/1 3.0%
Fecal Coliform 200/100 ml 29.3/100 ml 15%
Number of Samples Over 200% of Monthly Average Limit
Parameter 200% of Monthly Limit Number of Samples Over
BOD5 10 mg/L 0
TSS 60 mg/L 0
Ammonia N 4.0 mg/L 0

Number of Samples Over 200% of Weekly Average Limit
Parameter 200% of Weekly Limit Number of Samples Over
Fecal Coliform 800/100 ml 13
In addition to the exceptional test results,the Denton Wastewater Treatment Plant is in compliance
with all other criteria listed in Section B Approval Criteria of the October 22, 2012 guidance
document regarding reduction of monitoring frequencies.
We thank you for your consideration in these matters. If you have any additional questions or
comments,please call Troy Branch, Wastewater Plant ORC at 336/859-4460.
