: b. The " average weekly" mass discharge means the total discharge by weight during a calendar week divided by tne number of days in the week that the facility was operating. Where less than daily sampling is required by this permit, the average weekly mass discharge shall be determined by the summation of all the measured daily discharges by weight divided by the number of days during the calendar week when the measurements were made.

Either the volume of each individual sample is proportional to discharge flow rates, or the sampling interval (for constant volume samples) is proportional to the flow rates ever the time period used to produce the composite. The maximum time period between individual samples shall not exceed '2 hours except that for wastec of a uniform nature the samples may be collected on a frequency of at least twice per working shif t and shall be equally-spaced over a 24-hour period (or over the operating day if flows are of a shorter duration).

The term " publicly owned treatment works" or "POTW" means a f acility as defined by Section 212 of the Clean Water Act which is owned by a state or municipality, as defined by Section 502(4) of the Clean Water Act, including any sewers that convey wastewater to such a treatment works, but not including pipes, sewers cc other conveyances not connected to a facility providing treatment. The term also means the municipality as defined in Section 502(4) of the Clean Water Act which has jurisdiction over 'the indirect discharces to and the discharges f' rom such a treatment works.

(b) Any substantial change in the volume or character of pollutants being introduced into the POTW by an industrial user which was discharging into the POTW at the time of issuance of this permit.
(c)- Any change in the quality and quantity of effluent introduced into the POTW.
(d) The identity of significant industrial users served by the POTW which are subject to protreatment standards adopted under Section 307(b) of the Clean Water Act; the POTW shall aIso identify the character, and volume of . pollutants discharged-into the POTW by the. Industrial user" (2) The submission of the above information in the POTW's annual Wasteload Management Report, required under the provisions of 25 Pa. Code, Chapter 94, will normally be considered as providing adequate noti.co to the Department. However, if the above changes in industrial                  pollutant loadings to the POTW are significant enough to warrant either modification or revocation and reissuance of this permit, then the permittee is required to meet the provi-sions of Part B.1.a above.                                                                           ,

6 ATTACHMENT - NOTICE OF APPEAL 3(a).       Part C, requirement (h), of said Permit provides that:
                                         "Neither free available chlorine nor total residual chlorine may be discharged from any unit for more than two hours in any one day and not more than one unit in any plant may discharge free available or total residual chlorine at any one time unless the permittee can demonstrate to the Department that the units in a particular location cannot operate at or below this level of chlorination.
(b).
Appellant objects to Part C, requirement (h) in that it imposes an i'mmediately-ef fective standard upon Appellant's facility.                               Appellant has recently become aware that the chlorination limits specified by requirement (h) are inadequate to control biofouling at its unit.                         Appellant cannot operate its unit at or below the prescribed level of chlorination and desires to make a demonstration of this fact to the Department, as permitted by requirement (h).                                                 Promptly upon discovery of the inadequacy of the prescribed chlorination limits, Appellant advised the Department thereof by letter of December 24, 1984) copy attached as Exhibit B), and also advised the Department of its desire to perform the demonstration authorized by requirement (h).                           In order to conduct such a demonstration, levels of chlorination exceeding those levels specified by requirement (h) will be necessary.
If requirement (h) remains in force during the demonstration period, Appellant wil'1 be subject to
_ _ _ _ _ _ _ _ . _ _ --- _ __        n- . - _ - _

  . o' j                sanctions for exceedances of the chlorination level specified by requirement (h), thereby effectively denying Appellant the right to make its demonstration to the Department. Therefore, Appellant requests that the ef fectiveness of the chlorination limits specified by requirement (h) be suspended until Appellant has coaducted its demonstration and the Department's ruling 4                thereon has become final.
1 i
(c). Appellant further objects to requirement (h) in that                  .
4                the chlorination limits prescribed therein are ambiguous as to whether they apply to the dosing period or to the period of discharge into the river. The Department has by permit transmittal letter of November 26, 1984 (copy attached as Exhibit C) stated that it agrees with Appellant that the chlorination limits apply _only to the dosing period, but such interpretation has not been reflected in the Permit, thereby exposing Appellant to possible actions by third parties , or by the Department, arising from a contrary interpretation of requirement (h). Therefore, Appellant ' requests that requirement (h) be amended by adding the following provision at the end thereof:
                 "This limitation shall apply to the dosing period only."                      .
(d). Part A, pages 2e and 21 of said Permit establish the following effluent limitations for free available chlorine:
                  " Maximum Daily Concentration            -- 0.2 mg/l"
                  " Instantaneous Maximum Concentration -- 0.5 mg/1" These numerical limitations were taken by the Department from United Stated Environmental Protection 2

r-                              -
     \:*                                                       .
Agency standards published at 40 CFR 125 and 423. The Environmental Protection Agency standards, however, clearly apply to daily average concentrations and to daily maximum concentrations, respectively, while the limitations of the Permit are ambiguous. The Department has verbally agreed with Appellant. that the proper interpretation of the " maximum daily" limitation specified in the Permit is to apply the same to average daily discharge concentrations, in accordance with Environmental Protection Agency standards. This interpretation, however, is not reflected in the Permit, thereby exposing Appellant to possible actions arising from a contrary interpretation of the limitations. Therefore, Appellant requests that the free available chlorine effluent limitations specified at pages 2e and 21 of the Permit be amended to read as follows:
                            " Daily Average -- 0. 2 mg/l"
                            " Daily Maximum -- 0.5 mg/1"
              ,}}
