Or, if discharge is allowed, include: During this time period the permittee must comply with the limits in the following table:

  1. Additional information for the limits in Tables A1 and A2 above.

1)Include when using technology-based CBOD5 limits:The CBOD5 concentration limits are considered equivalent to the minimum design criteria for BOD5 specified in OAR Chapter 340, Division 41.

2)Average dry weather design flow to the facility equals XX MGD[14]. Mass load limits[15] are based on XX MGD.

3)Mass load limits for older facilities are supposed to be based on the Design Average Wet Weather Flow (AWWF). In the case of some older facilities, they may not be, and the AWWF may not even be known. If this is the case and the permit holder is requesting new AWWF-based mass load limits for wintertime flows, include the following:In accordance with OAR 340-041-0061(9)(d), the mass load limits are interim limits. Within 12 months of permit issuance, the permittee must submit to DEQ the design average wet weather flow and hydraulic secondary treatment capacity. Upon review and approval of the design flow information, DEQ may modify the permit and include final mass load limits as described in OAR 340-041-0061(a).

If summer period concentration limits are higher than the basin’s minimum design criteria, include[16]:In accordance with OAR 340-041-0061(3)(c), compliance with the more stringent minimum design criteria that apply to this basin in the summer period will be deferred until it is necessary to expand or otherwise modify or replace the existing treatment facilities.

  1. Additional Parameters. Permittee must comply with the limits in the following table (year round except as noted):

Table A3: Limits for Additional Parameters

Year-round
(except as noted) / Limits (bacteria limits assume no bacteria TMDL in place)
BOD5or CBOD5 and TSS Removal Efficiency / May not be less than 85% monthly average for BOD5or CBOD5 and TSS with systems where preliminary treatment occurs in septic tanks, such as STEP systems, include: (see Note a.)
Note: the 85% can be reduced for lagoons, trickling filters and when influent is less concentrated. See 40 CFR 133.103.
Include the following dischargers with TMDL temperature WLA(Waste Load Allocation):
Temperature / Expressed as (choose one): Maximum 7 day rolling average ETL or Daily Maximum ETL (Excess Thermal Load)
Effluent Flow (for permit holders who have elected to build storage capacity to reduce temperature impact) / Daily Maximum
Include the following for discharges to freshwater and estuarine waters other than shellfish growing waters:
E. coli Bacteria(see Note b.) / Monthly geometric mean may not exceed 126 organisms per 100 ml.
No single sample may exceed 406 organisms per 100 ml.
Include the following for discharges to marine and estuarine shellfish growing waters (for help in delineating, refer to Bacteria IMD):
Fecal Coliform Bacteria / Monthly Median concentration may not exceed 14 organisms per 100 ml.
No more than 10% of the samples collected in a calendar month may exceed 43 organisms per 100 ml.
Include the following for discharges to coastal areas with primary contact recreation uses (for help, refer to Bacteria IMD):
Enterococcus Bacteria / Monthly geometric mean may not exceed 35 organisms per 100 ml.
pH / If compliance is to be established with respect to grab samples:
May not be outside the range of XX to XX S.U.
If compliance is to be established with respect to continuous monitoring:
May not be outside the range of XX to XX for more than a total of 7 hours and 26[17] minutes in any calendar month, and no individual excursion from this range may exceed 60 minutes.
Chlorine, Total Residual / Monthly average concentration may not exceed XX mg/L. Daily maximum concentration may not exceed XX mg/L (see Note c. )Include this note only if the chlorine limit is less than 0.05 mg/L. Otherwise delete.
Other limits / For example: ammonia. Note: limits should be expressed in concentration and mass whenever possible[18].
Notes update lettering as necessary
  1. Include the following with systems where preliminary treatment occurs in septic tanks, such as STEP systems: Due to preliminary treatment that occurs within the septic tanks, the influent BOD5 and TSS concentrations are assumed to be 200 mg/L for calculation of the percent removal efficiency.[19]
  2. No single E. coli sample may exceed 406 organisms per 100 mL; however, DEQ will not cite a violation of this limit if the permittee takes at least 5 consecutive re-samples at 4 hour intervals beginning within 28 hours after the original sample was taken and the geometric mean of the 5 re-samples is less than or equal to 126 E. coli organisms/100 mL.[20]
  3. When the total residual chlorine limitation is lower than 0.05 mg/L, DEQ will use 0.05 mg/L as the compliance evaluation level; that is, daily maximum concentrations at or below 0.05 mg/L will be considered in compliance with the limit.[21]

If there is a mixing zone, include the following:

2.Regulatory Mixing Zone

Pursuant to OAR 340-041-0053, the permittee is granted a regulatory mixing zone as described below:

Insert mixing zone description. Note: if current description contains the phrase “shall be defined as”, replace with “is”.

Include the following in all permits unless there are groundwater concentration limits:

3.Groundwater Protection

The permittee may not conduct any activities that could cause an adverse impact on existing or potential beneficial uses of groundwater. All wastewater and process related residuals must be managed and disposed of in a manner that will prevent a violation of the Groundwater Quality Protection Rules (OAR Chapter 340, Division 40).

Include the following in all permits that cover recycled water:

4.Use of Recycled Water

The permittee is authorized to distribute recycled water if it is:

  1. Treated and used according to the criteria listed in Table A4[22].
  2. Managed in accordance with its DEQ-approved Recycled Water Use Plan[23] unless exempt as provided in Schedule D, condition 4.b?.
  3. Used in a manner and applied at a rate that does not have the potential to adversely impact groundwater quality[24].
  4. Applied at a rate and in accordance with site management practices that ensure continued agricultural, horticultural, or silvicultural production and does not reduce the productivity of the site[25].
  5. Irrigated using sound irrigation practices to prevent:
  6. Offsite surface runoff or subsurface drainage through drainage tile;
  7. Creation of odors, fly and mosquito breeding, or other nuisance conditions; and
  8. Overloading of land with nutrients, organics, or other pollutants[26].

Delete rows in Table A4 pertaining to higher classes of treated water than the permittee can achieve. Failure to do so may make determining compliance on DMRs difficult. If the permittee wants the permit to include lower classes of treatment, this is allowable provided the corresponding use(s) of the recycled water are described in the recycled water use plan.

Table A4: Recycled Water Limits

Class / Level of Treatment
