The daily discharge expressed as concentration (in mg/l) shall be calculated by dividing total of measurement readings by number of sample collected during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. The daily discharge expressed as loading rate (in pounds/day) is calculated by using this formula {daily average concentration (mg/l) x the same day total flow (in

million gallons) x 8.34}.

2. “Weekly average (maximum or minimum)" limitation means the highest or lowest

allowable average of "daily discharges'' over a calendar week, calculated as the sum of all "daily discharges'' measured during a calendar week divided by the number of "daily discharges'' measured during that week. Each of the following 7- day periods is defined as a calendar week: Week 1 is Days 1 - 7 of the month;

Week 2 is Days 8 - 14; Week 3 is Days 15 - 21; and Week 4 is Days 22 - 28. For weekly average maximum, if the "daily discharge" on days 29, 30 or 31 exceeds the "weekly average" discharge limitation, MDE may elect to evaluate the last 7 days of the month as Week 4 instead of Days 22 - 28. For weekly average minimum, if the "daily discharge" on days 29, 30 or 31 is lower than the "weekly average" discharge limitation, MDE may elect to evaluate the last 7 days of the

month as Week 4 instead of Days 22 - 28.

A. Effluent Limitations, Continued An annual average flow of 0.542 million gallons per day (mgd) was used in waste allocation calculations (expressed as waste loading rate limit), and this unit shall be used when reporting on the Discharge Monitoring Report (DMR) as required by General Condition III.A.2. Notification is to be provided to the Department at least 180 days before the annual average flow is expected to exceed this flow level. If a permit modification is required,

the Department will initiate the public participation NPDES process. Because this facility is authorized to discharge only 4 months per year, the permitted flow is equivalent to a minor facility.

Footnotes for effluent limitations:

(1) When this permit is renewed, the new limitations may not be equal to the above limitations. There shall be no

discharge of floating solids or visible foam other than trace amounts.

(2) The permit may also be reopened in accordance with the requirements of MDE's Watershed Permitting Plan under

which all discharge permits in a watershed are issued the same year.

(3) The specific designated use of Corsica River of the Lower Chester River Mesohaline segment is Use II – Support of

Estuarine and Marine Aquatic Life and Shellfish Harvesting. The Maryland Department of the Environment (MDE) has identified the waters of the Corsica River of the Lower Chester River Mesohaline segment on the State’s Integrated Report as impaired by the following pollutants (listing year and Integrated Report Assessment Unit Identification in parentheses): total suspended solids (1996; MD-CHSMH), nutrients (1996; MD-CHSMH), fecal

coliform (1996; MD-CHSMH-Corsica_River), and polychlorinated biphenyls (PCBs) in fish tissue (2002; MD- CHSMH-02130507) and impacts to biological communities (2004; MD-CHSMH). Nutrients, fecal coliform, and PCB TMDLs for the restricted shellfish harvesting portion of the Corsica River were approved by the US EPA in 2000, 2005, and 2011 respectively. This permit is in conformance with these TMDLs and the “Chesapeake Bay

TMDL for Nitrogen, Phosphorus, and Sediment” established on December 29, 2010. When TMDLs for other remaining parameters are completed, limits may be imposed, after the public participation process, to incorporate any TMDL requirements.

(4) The loading caps for the Centreville WWTP for the seasonal stream discharge from December 1 through March 31,

equal to 3,004 pounds for TN and 457 pounds for TP. The permittee shall also comply with the monthly loading cap limits of 750 lbs/month and 140 lbs/months for TN and TP respectively. The first exceedance of the permit limit shall be counted and reported as daily exceedances beginning from the first exceedance, determined to the nearest day, through March 31. In addition, after any such exceedance, the permittee shall demonstrate to the Department's

satisfaction that the facility is optimizing its nutrient removal capability, and neither the arrival of the next season (December 1 thru March 31) nor the issuance of a permit renewal during a period of noncompliance shall obviate continuance of any noncompliance status related to treatment optimization requirements.

(5) The current plant operates the Biological Nutrient Removal (BNR) process on a year round basis and the Town is also

authorized under groundwater permit GW 14-DP-3323 to operate the spray irrigation system 365 days a year.

Consequently, the level of nutrient control that is achieved by the combined surface water and ground water systems is equivalent to Enhanced Nutrient Removal (ENR) level treatment and an ENR upgrade at this plant is not required.

(6) The permittee may request that the permit be reopened and modified to include nutrient trading consistent with the

most current “Maryland Policy for Nutrient cap Management and Trading in Maryland’s Chesapeake Bay Watershed” in effect at that time.

(7) Total residual chlorine limitation of the nondetectable level shall be applicable, when chlorine or any chlorinecontaining compound is used in any treatment process(es), including but not limited to disinfection, that could become

a potential constituent of the effluent discharged from the Centreville WWTP. The wastewater shall be dechlorinated to reduce effluent total residual chlorine concentration to the nondetectable level (See definition I.M).

(8) In accordance with 40CFR §133.102, the 30-day average percent removal for BOD and TSS shall not be less than 85

5 (eighty-five) percent as the minimum level of effluent quality attainable by the secondary treatment. Refer to the footnotes 22 and 23 for further details for calculations and reporting requirements toward compliance to the BOD 5 and TSS percent removal effluent limitations (See Definition I.T).

(11) The monitoring of total phosphorus, total ammonia nitrogen, TKN, (nitrite + nitrate)-N and orthophosphate

shall be two per week 24 hour composite samplings.

(12) Total nitrogen as N (in mg/l) is a calculated parameter as the sum of individual results for total ammonia

nitrogen as N, organic nitrogen as N and (nitrite + nitrate) as N. Total Kjeldahl Nitrogen (TKN) is defined as the total concentration of organic nitrogen and ammonia as N. All nitrogen species must be sampled at the same day. The monitoring result for organic nitrogen may be calculated through the subtraction of the total Ammonia as N monitoring result from the result of TKN sample taken at the same day.

(13) The permittee shall also calculate and report on the DMR the TN and TP total monthly loads (Definition

I.H.5) plus seasonal cumulative December 1 thru March 31loads (Definition I.H.6) for the outfall- 001A.

(14) The Minimum monitoring requirements of Two per day-grab samplings for total residual chlorine shall be

applicable, when chlorine or any chlorine compound is used in any treatment process(es), including but not limited to disinfection, that could become a potential constituent of the effluent discharged from the Centreville WWTP. The minimum level (quantification level) for total residual chlorine is 0.10 mg/l. The permittee may report all results below the minimum level as <0.10 mg/l. All results reported below the

minimum level shall be considered in compliance.

In accordance with 40 C.F.R. § 122.44(i)(1)(iv), the permittee shall use sufficiently sensitive test procedures (i.e., methods) approved under 40 C.F.R.

Part 136

or required under 40 C.F.R. Chapter I, Subchapter N or O, for the analysis of pollutants or pollutant parameters limited in this permit. A method is considered “sufficiently sensitive” when either: (1) the method minimum level (ML) is at or below the level of the effluent limit established in this permit for the measured pollutant or pollutant parameter; or (2) the method has the lowest ML of the analytical methods approved under 40 C.F.R. Part 136 or required

under 40 C.F.R. Chapter I, Subchapter N or O for the measured pollutant or pollutant parameter. The ML is not the minimum level of detection, but rather the lowest level at which the test equipment produces a recognizable signal and acceptable calibration point for a pollutant or pollutant parameter, representative of the lowest concentration at which a pollutant or pollutant parameter can be measured with a known level of confidence. For the purposes of this permit, the

detection limit is the lowest concentration that can be reliably measured within specified limits of precision and accuracy for a specific laboratory analytical method during routine laboratory operating conditions (i.e., the level above which an actual value is reported for an analyte, and the level below which an analyte is reported as non-detect).
