PERMITTED ACTIVITIES[11]

Until this permit[12] expires or is modified or revoked, the permittee is authorized to: 1) operate a wastewater collection, treatment, control and disposal system; and 2) discharge treated wastewater to waters of the state only from the authorized discharge point or points in Schedule A in conformance with the requirements, limits, and conditions set forth in this permit[13],[14].

Unless specifically authorized by this permit, by another NPDES permit, or by Oregon statute or administrative rule, any other direct or indirect discharge of pollutants to waters of the state is prohibited.

Instructions to permit writers:

This document has been formatted using Styles. This means that for each piece of text in the document, a format has been defined. To see the list of Styles used in the document, click on the little arrow as shown below.

This should bring up a box that lists all the styles used in the document. When you click on text in the document (except for instructions and some parts of tables), the name of the style will become highlighted. You can change it by clicking on a different style. When you add text to the document, select the style that you want for it.

Example: when you add a new section and you want the title to appear in the Table of Contents, select the title and the style called “1. Permit Hanging 1(TOC)” in the Style box. When you update the document (see instructions below), the numbering and Table of Contents will update automatically.

Whenever you copy new language into the permit template, be sure and do it as follows:

When you paste, use “Paste Special” and then select “Unformatted Unicode Text”.

This is very important! It will keep the permit template from getting corrupted.

To finalize the document:

  1. Delete the endnotes. Instructions are below.
  2. Add in the correct version of Schedule F.
  3. Update the Table of Contents, List of Figures, table numberings and section numberings as follows: select the entire document and hit F9. That’s it!
  4. Update all the references to tables and sections throughout the document. Doing a search on “?” will help you find them.
  5. Make sure there is no remaining highlighting, colored fonts, capital Xs, [PERMITTEE NAME] or question marks in the document.
  6. Do one last update of the Table of Contents and List of Tables. To do this for the Table of Contents, put your cursor anywhere on the Table of Contents, right-click and select “Update field”. In the dialog box, select “Update entire table”. Follow the same process for the List of Tables.

To delete endnotes, just do a find-and-replace in which you replace all of the endnotes with nothing. Here is more detail:

  • Click on “Find”.
  • In the “Find and Replace” dialogue box, click on “More>” and then “Special” (it is at the bottom of the box).
  • Select “Endnote Mark”.
  • Click on “Replace All”.

Other Limits / mg/L

Notes:
  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.Regarding the 85% removal, this can be reduced for lagoons, trickling filters and when influent is less concentrated. See 40 CFR 133.103.
  2. Only applies to discharges to freshwater and estuarine waters other than shellfish growing watersNo single E. coli sample may exceed 406 organisms per 100 mL; The permittee may take at least 5 consecutive re-samples at 4 hour intervals beginning within 48 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 to demonstrate compliance with the limit.
  3. If compliance is to be established with respect to grab samples:May not be outside the range of X.X to X.X 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[15] minutes in any calendar month, and no individual excursion from this range may exceed 60 minutes.
  4. Only applies for discharges to marine and estuarine shellfish growing waters.
  5. Only applies for discharges to coastal areas with primary contact recreation uses.
  6. DEQ has established a minimum Quantitation Limit of 0.05 mg/L for Total Residual Chlorine. In cases where the average monthly or maximum daily limit for Total Residual Chlorine is lower than the Quantitation Limit, DEQ will use the reported Quantitation Limit as the compliance evaluation level.
  7. Reported as a monthly geometric mean

ii.Additional information for the limits in Table A1 above.

(A)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.

(B)Average dry weather design flow to the facility equals XX MGD[16]. Mass load limits[17] are based on XX MGD.

(C)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 permittee 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).

(D)If summer period concentration limits are higher than the basin’s minimum design criteria, include[18]: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. Regulatory Mixing Zone

[Include if there is no mixing zone] There is no regulatory mixing zone for this discharge[19].

[Include if there is a 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”].

  1. Groundwater Protection

The permittee may not 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 not cause a violation of the Groundwater Quality Protection Rules (OAR Chapter 340, Division 40).

  1. Use of Recycled Water

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

b.Treated and used according to the criteria listed in Table A4[20].

c.Managed in accordance with its DEQ-approved Recycled Water Use Plan[21] unless exempt as provided in Schedule D, condition 5?.

d.Used in a manner and applied at a rate that does not have the potential to adversely impact groundwater quality[22].

e.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[23].

f.Irrigated using sound irrigation practices to prevent:

i.Offsite surface runoff or subsurface drainage through drainage tile;

ii.Creation of odors, fly and mosquito breeding, or other nuisance conditions; and

iii.Overloading of land with nutrients, organics, or other pollutants[24].

Earlier versions of the permit template directed the permit writer to delete rows in Table A2 pertaining to higher classes of treated water than the permittee can achieve, on the grounds that failure to do could make determining compliance on DMRs difficult. Permit writers are now advised to leave any type of treatment in the permit that has a reasonable likelihood of being employed during the permit cycle, so as to preclude the need for a permit modification if the permittee decides to change their level of treatment.

Table A2: Recycled Water Limits
