LbsMonthly WeeklyBOD5 or CBOD5 upon requestTSS

iii. Additional information for the limits in Tables A1 and A2 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 MGD15. Mass load limits16 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, include17: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.

b. Additional Parameters.

Permittee must comply with the limits in the following table (year-round except as noted):

Table A2: Limits for Additional Parameters

Year-round(except as noted)

Limits (bacteria limits assume no bacteria TMDL in place)

BOD5 or CBOD5 and TSS Removal Efficiency

May not be less than 85% monthly average for BOD5 or CBOD5 and TSS. With systems where preliminary treatment occurs in septic tanks, such as STEP systems, include reference to Note a. Regarding the 85% removal, this can be reduced for lagoons, trickling filters and when influent is less concentrated. See 40 CFR 133.103.

Include the following for dischargers with TMDL temperature WLAs(Waste Load Allocations):Temperature Expressed as (choose one): Maximum 7 day rolling average ETL or

Daily Maximum ETL (Excess Thermal Load)Effluent Flow (for permittees 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 log mean (same as geometric mean18) may not exceed 126

organisms per 100 ml.No single sample may exceed 406 organisms per 100 ml.



Year-round(except as noted)

Limits (bacteria limits assume no bacteria TMDL in place)

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 2619 minutes in any calendar month, and no individual excursion from this range may exceed 60 minutes.

Chlorine, Total Residual20 The monthly average effluent concentration limit is XX mg/L. The daily maximum effluent concentration limit is XX mg/L.

Include if applicable:DEQ has established a minimum Quantitation Limit of 0.05 mg/L21 for Total Residual Chlorine. In cases where the monthly average or daily maximum limit for Total Residual Chlorine is lower than the Quantitation Limit, DEQ will use the reported Quantitation Limit as the compliance evaluation level.

Other limits Example: ammonia. Note: limits should be expressed in concentration and mass whenever possible22. Exceptions include those parameters which are neither conservative nor bioaccumulat-ive. Ammonia again is an example: it oxidizes rapidly into nitrate and so cumulative effectives outside the mixing zone are not a concern.

Notes: (update lettering as necessary)a. 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. 23

b. 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. 24

2. Regulatory Mixing Zone

[Include if there is no mixing zone] There is no regulatory mixing zone for this discharge25.



[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”].

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).

4. Use of Recycled Water

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

a. Treated and used according to the criteria listed in Table A426.

b. Managed in accordance with its DEQ-approved Recycled Water Use Plan27 unless exempt as provided in Schedule D, condition 5?.

c. Used in a manner and applied at a rate that does not have the potential to adversely impact groundwater quality28.

d. 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 site29.

e. 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 pollutants30.

Earlier versions of the permit template directed the permit writer to delete rows in Table A4 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.

By the end of the twenty fourth month [timeframe is at discretion writer but must not exceed 24 months] after permit issuance, the permittee must submit an MMP (Mercury Minimization Plan) for approval. At a minimum, the MMP must include the following:

a. Identification and evaluation of current and potential mercury (both MeHg and total) sources

b. Identification and evaluation of conditions (i.e., anaerobic conditions) that might contribute to the methylation of elemental mercury in the collection and treatment systems

c. Identification of industrial, commercial and residential sources of mercury

d. A monitoring plan to confirm current or potential sources of mercury (Monitoring Plan)

e. Identification of potential methods for reducing or eliminating mercury. These may include but are not limited to:

i. BMP requirements or limits for industrial and commercial sources of mercury to a collection system

ii. Material substitution

iii. Material recovery

iv. Spill control and collection

c. Industrial User Monitoring in Lieu of Self-Monitoring

Where the permittee elects to conduct monitoring of an industrial user in lieu of requiring self-monitoring, the permittee must gather all information which would otherwise have been submitted by the user. The permittee must also perform the sampling and analyses in accordance with the protocols established for the user and must follow the requirements in 40 CFR § 403.12(g)(2) if repeat sampling is required as the result of any sampling violation(s).

d. Sample Collection and Analysis

Sample collection and analysis, and the gathering of other compliance data, must be performed with sufficient care to produce evidence admissible in enforcement proceedings or in judicial actions. Unless specified otherwise by the Director in writing, all sampling and analyses must be performed in accordance with 40 CFR part 136 or 40 CFR part 503 for biosolids analytes.

8. Slug Control Plans

The permittee must evaluate whether each Significant Industrial User needs a slug control plan or other action to control slug discharges. Industrial Users identified as significant after October 14, 2005, must be evaluated within 1 year of being designated a Significant Industrial User. A slug discharge is any discharge of a non-routine, episodic nature, including but not limited to an accidental spill or a non-customary batch discharge that has a reasonable potential to cause interference or pass through or in any other way violate the permittee’s regulations, local limits, or conditions of this permit. Per 40 CFR Part 403:8(f)(2)(vi), the permittee is required to track and document any slug discharge by Significant Industrial Users and make it available to DEQ upon request. The permittee must require Significant Industrial Users to immediately notify the permittee of any changes at its facility affecting potential for a slug discharge. If the permittee determines that a slug control plan is needed, the requirements to control slug discharges must be incorporated into the Significant Industrial User’s control mechanism and the slug plan must contain, at a minimum, the following elements:



a. Description of discharge practices, including non-routine batch discharges;

b. Description of stored chemicals;

c. Procedures for immediately notifying the permittee of slug discharges, including any discharge that would violate a prohibition under 40 CFR § 403.5(b) with procedures for follow-up written notification within five days; and

d. If necessary, procedures to prevent adverse impact from accidental spills, including inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site run-off, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents), and/or measures and equipment for emergency response.

9. Enforcement

The permittee must identify all violations of the industrial user's permit or local ordinance. The permittee must investigate all such instances of industrial user noncompliance and take all necessary steps to return users to compliance. The permittee’s enforcement actions must follow its approved legal authorities (for example, ordinances) and Enforcement Response Plan developed in accordance with 40 CFR § 403.8(f)(5). The permittee must periodically review administrative penalties to ensure that the penalties serve as an effective deterrent of noncompliance.

10. Public Notice of Significant Noncompliance

The permittee must publish annual notification in a newspaper(s) of general circulation that provides meaningful public notice within the jurisdiction(s) served by the permittee of industrial users which, at any time during the previous 12 months, were in significant noncompliance with applicable pretreatment requirements. For the purposes of this requirement, an industrial user is in significant noncompliance if it meets one or more of the criteria listed in 40 CFR § 403.8(f)(2)(viii).

11. Data and Information Management

The permittee must develop and maintain a data management system designed to track the status of the industrial user inventory, discharge characteristics, and compliance. In accordance with 40 CFR § 403.12(o), the permittee must retain all records relating to pretreatment program activities for a minimum of 3 years and make such records available to DEQ and EPA upon request. The permittee must also provide public access to information considered effluent data under 40 CFR part 2.

12. Annual Pretreatment Program Report

The permittee must submit a complete report to DEQ on or before March 31 that describes the pretreatment program activities during the previous calendar year pursuant to 40 CFR § 403.12(i) 105. For guidance on the content and format of this report, contact DEQ’s pretreatment coordinator. Reports submitted to DEQ regarding pretreatment must be signed by a principal executive officer, ranking elected official or other duly authorized employee if such employee is for overall operation of the POTW106.

13. Pretreatment Program Modifications

The permittee must submit in writing to DEQ a statement of the basis for any proposed modification of its approved program and a description of the proposed modification in accordance with 40 CFR § 403.18. No substantial program modifications may be implemented by the delegated program prior to receiving written authorization from DEQ.



SCHEDULE F: NPDES GENERAL CONDITIONS

For this Schedule to appear in the Table of Contents, do not delete the above. Insert the appropriate version of the General conditions. These may be found at:

General Conditions - all versions

This link is from the Permit Development sharepoint page.


1 The lat/long for the outfall can be obtained from the Outfall Location Tool at http://deq05/wqoutfalls/EOPbasics.aspx. It may also be obtained from the permit application or other method such as Google Maps.

2 In the past, information on the facility type has been included on the face page of the permit along with the facility location. Since this information can potentially trigger the need for a permit modification if the treatment technology changes, it is no longer included. Note that even without such a description, the permit may still need to be modified as the result of a treatment modification if the modifications mean that different TBELs (which includes basin standards) apply, or if the change(s) in process or facility create the need for different permit conditions.3 Oregon’s water quality criteria (found in OAR 340-041-0101 through 340-041-0350) are developed for specific basins defined by the Oregon Water Resources Department (WRD). A map of these basins may be found at: http://www.deq.s-tate.or.us/wq/rules/div041/basinmap.pdf. The LLID tool is scheduled to be modified so that it may be used to determine the WRD basin. Until this is complete, call GIS specialist at (503)229-6798. 4 If no street address is available, lat/long should be provided.

5USGS subbasin names are used in TMDL development. A map of the USGS subbasins in Oregon may be found at: http://www.deq.state.or.us/wq/assessment/usgssubbasinmap.htm. For a comparison of the USGS and WRD systems, go to http://deq05/wq/wqpermits/Tools/BasinNamingConventions.pdf

6 Confirm that the LLID is correct and that it is a named stream. If you have to, go downstream until you find a named stream and use that LLID. The LLID is two parts. Part 1 is the LLID of the named stream. Part 2 is the river mile (the discharge location into a named stream or if the discharge is to an unnamed tributary, where that tributary enters a named stream). The river mile should be updated from the LLID maps. In the past, there was a 3rd part, which was a letter suffix. As of 10/1/2014, the suffix should no longer be used.

7 Include treatment level as per the Wastewater System Classification Worksheet. 8

This number uniquely identifies the permit to the EPA. It is assigned by SIS. Within PCS, this number indicates the permit type (e.g., Standard, General, Stormwater General).9

This statement is included on the permit face to ensure that DEQ actions (e.g., permits, certifications) that affect land use are in accordance with state land use planning goals and city and county comprehensive land use plans (OAR Chapter 340, Division 18). Rather than have DEQ staff review local land use regulations to determine whether a DEQ action is compatible with local land use regulations, DEQ requests the assistance of local governments through the completion of a Land Use Compatibility Statement (LUCS). If the local government completes the LUCS in the affirmative (checks “yes”), DEQ may rely on the LUCS to indicate compatibility with local land use requirements and, because state land use goals are implemented through local land use regulations, DEQ may also use the LUCS to demonstrate that its actions are compatible with state goals. If a LUCS is checked “no” or contains additional information, further work will need to be done to ensure that DEQ’s action complies with local land use regulation and state land use goals. For renewals, the permit writer usually only reviews the LUC if the facility is being remodeled or if increased limits are requested. See OAR 340-018-0050(2)(b) for more detail. The LUCS form is available on DEQ’s web page: http://www.deq.state.or.us/pubs/permithandbook/lucs.htm10

This date is to be entered by the permit coordinator, and it is 20 days from the date the permit is signed and mailed (the issuance date). This is consistent with the definition of the permit effective date in OAR 340-045-0035. 11

Some NPDES permits issued by DEQ refer to both “waters of the state” and “public waters”. Though OAR Division 45 (“Regulations Pertaining to NPDES and WPCF Permits”) uses these terms interchangeably, the permit template uses the term “waters of the state” exclusively to reduce the potential for confusion.

12 See OAR 340-045-0080 entitled “Effect of a Permit”.

13 See OAR 340-045-0015 entitled “Permit Required”.

14 See OAR 340-0045-0080 entitled “Effect of a Permit”. 15

The average dry weather design flow (ADWDF) should be included in the permit. In addition to being used to develop mass load limits for most permits, it is used to determine monitoring requirements and permit fees.

16 See OAR 340-041-0061(9) for rules on how mass load limits are calculated. A graphical representation of OAR 340-041-0061(9)(a) through (e) may be found at: http://deq05/wq/wqpermits/docs/MassLoadLimitDecisionTree.pdfAs described in the OAR and explained in the graph, mass load limits may be based on average dry weather flow, average wet weather flow, a TMDL waste load allocation, or they may be established by the EQC. The date that a

wastewater treatment plant was built (before or after June 30, 1992) can also determine how mass load limits are calculated.

17 This language must be included in the permit as per OAR 340-041-0061(3)(c).

18 The 2004 Bacteria position paper uses the term log mean and geometric mean interchangeably, while the Bacteria Rule (OAR 340-041-009) simply uses the term log mean. This is unfortunate because log mean can be confused with logarithmic average which is something different (see Wikipedia at http://en.wikipedia.org/wiki/Geometric_mean#Log-average). The permit template includes both log mean and geometric average to avoid the confusion that could result from using the term log mean by itself.

19 This is equivalent to 1% of a 31 day month.

20 Former versions of the permit template asked the permittee to report the amount of chlorine used. This information is not as useful as total residual chlorine and so the requirement is no longer included. 21 DEQ Quality Assurance Officer Scott Hoatson with the DEQ Lab says that according to Standard Methods procedures, the lowest detectable concentration under ideal conditions is between 0.010 mg/L and 0.020 mg/L. Wastewater however does not represent ideal conditions. Scott therefore suggests no less than 0.050 mg/L for wastewater. He also suggests that for some industrial wastes we may need to go to 0.10 mg/L (e.g. fish processing).22 See federal regulations. 40 CFR § 122.45(f).

23 This note applies to STEP systems only. It was developed by Western Region permitting staff using Best Professional Judgment. The reason DEQ has decided to assume that influent BOD5 and TSS concentrations are 200 mg/L is that the municipalities that have such systems are typically very small, and have limited ability to establish performance-based limits.

24 Permittees may have additional time if they have a hardship exemption. The basis for the hardship is based on the particulars of the permittee’s situation. The permittee should negotiate the shortest practicable time with the permittee and specify it in the permit. In no case should the time exceed 72 hours.

25 Past versions of the permit template have included the following language: All effluent limitations must be met at the end of the outfall pipe. No wastes may be discharged or activities conducted that cause or contribute to a violation of water quality standards in OAR 340-041 applicable to the XXX basin except as provided for in OAR 340-045-0080. DEQ has elected to remove the first sentence because it is redundant. DEQ has elected to delete the second sentence because it may create confusion on the applicability of the permit shield rule in OAR 340-045-0080(1). 26

See OAR 340-055-0012(2) which is as follows: Any person who uses recycled water may use recycled water only for the beneficial purposes described in this rule, and must comply with the standards and requirements of this rule and the rules of this division.27 See OAR-055-016(2).

28 This is required to comply with OAR 340-055-0020.29 See ORS 215.246(a). The complete reference is as follows:

215.246 Approval of land application of certain substances; subsequent use of tract of land; considera-tion of alternatives. (1) The uses allowed under ORS 215.213 (1)(y) and 215.283 (1)(v): (a) Require a determination by the Department of Environmental Quality, in conjunction with the department’s review of a license, permit or approval, that the application rates and site management practices for the land application of reclaimed water, agricultural or industrial process water or biosolids ensure continued agricultural, horticultural or silvicultural production and do not reduce the productivity of the tract.

30 These are good management practices to prevent water quality impacts and nuisance conditions as well as meet the requirements of ORS 215.246(1)(a) that requires DEQ to determine that the application rates and site management practices "ensure continued agricultural, horticultural or silvicultural production and do not reduce the productivity of the tract."

31 The rules don’t specify what “oxidized” means. The term is not intended to prescribe a form of treatment, instead it is intended to ensure recycled water is treated to the point that it is not putrid.

32 The permittee is required to filter the water even if they can meet the NTU levels without filtration.

http://en.wikipedia.org/wiki/Geometric_mean#Log-average

http://en.wikipedia.org/wiki/Geometric_mean#Log-average

33All new facility designs should be consistent with OAR 340-055-0012(7)(c)(A) to place filtration before disinfection. Since the reverse design is a poor engineering practice, legacy facilities are expected resolve the design problem during future plant upgrades.

34 In the event that a permittee collects multiple samples on a single day, the accepted practice is that the permittee should report the median of all the samples collected on that day. This median value is then one of the required 7 values. See OAR 340-055-0012(7)(c) and (d) for Class A recycled water.


36 In the event that a permittee collects multiple samples on a single day, the accepted practice is that the permittee should report the median of all the samples collected on that day. This median value is then one of the required 7 values. See OAR 340-055-0012(6)(c) and (d) for Class B recycled water.


38 In the event that a permittee collects multiple samples on a single day, the accepted practice is that the permittee should report the median of all the samples collected on that day. This median value is then one of the required 7 values. See OAR 340-055-0012(5)(c) and (d) for Class C recycled water.

39 The rules don’t specify what “oxidized” means. The term is not intended to prescribe a form of treatment. Rather the term is intended to ensure recycled water is treated to the point that it is not putrid.


41 This phrase clarifies that the conditions apply to biosolids that are added to other products.

42 See OAR 340-050-0015(4) and OAR 340-050-0015(9).

43 This clause allows DEQ to approve rates over the agronomic rate at reclamation sites on a case-by-case basis.

44 See OAR 340-050-0025(3).

45 See OAR 340-050-0030(1).

46 See OAR 340-050-0026(2)(b).

47 See OAR 340-050-0026(2)(c).

48 See OAR 340-050-0026. The Biosolids IMD (http://www.deq.state.or.us/wq/pubs/imds/biosolids.pdf) describes pathogen reduction (PR) and vector attraction reduction (VAR) options. DEQ’s Biosolids Specialist may also be contacted. Alternatives to the primary PR and VAR methods may be used when identified in the approved BSMP. The BSMP should require that DEQ be notified when alternate methods are used. Additional methods may be added to the BSMP during the term of the permit without public notice, because changes to PR and VAR measures are not part of the land application plan. For more information, contact Biosolids Specialist at 503-229-5472.

49 See OAR 340-050-0026(2)(a). The term “ceiling concentration” was chosen instead of say, maximum concentration, in order to be consistent with state and federal regulations. The term “pollutant concentration” was chosen in order to be consistent with state and federal regulation.

50 For more information, refer to the Significant Figures IMD at http://www.deq.state.or.us/wq/pubs/imds/Sig-FigsIMD.pdf

51 Permit writer should consult with permittee regarding the best description to use. It is important that the location description not restrict permittee from changing treatment technology or upgrading facilities for the duration of the permit, while at the same time it should be sufficiently specific that samples are collected in a consistent fashion.

52 For flow-through facilities, the monitoring location should be either on the influent or the effluent. If the facility has

http://www.deq.state.or.us/wq/pubs/imds/SigFigsIMD.pdf

http://www.deq.state.or.us/wq/pubs/imds/biosolids.pdf

storage (such as lagoon treatment system), require monitoring on both the influent and effluent.


54 For continuous monitoring requirements, consider specifying backup monitoring procedure (either grab or backup continuous monitor) in the event of equipment failure.

55 For flow-through facilities, the monitoring location should be either on the influent or the effluent. If the facility has storage (such as lagoon treatment system), require monitoring on both the influent and effluent.

56 The Monitoring Matrix may be found on the Permit Writers’ Corner under the Monitoring heading at: http://deq05/wq/wqpermits/PCGuidance.htm#MR

57 Example: ETL= Qe x (Te-Twq) x C. Check TMDL for formula to use.

58 The Medford permit includes the following language regarding flow monitoring and it is provided as an example for when the permittee relies on gages maintained by others for instream flow.

Note B1: The following applies to continuous monitoring when used for the parameters in Schedule B above:a. DEQ must approve the use of stream monitoring data collected by another entity (for example, USGS)

prior to being used; andb. DEQ acknowledges that uninterrupted data collection is not guaranteed. In the event of equipment failure

or less, the permittee must notify DEQ and deploy repaired or new equipment to minimize interruption of data collection. During any period of data loss beyond the reasonable control of the permittee, temperature and/or pH may be estimated by any method acceptable to DEQ.

Note B5: Receiving stream flow rate may be derived from the USGS gauging stations 4339000 Rogue River at Dodge Bridge, near Eagle Point, and USGS gage 14348000 Little Butte Creek Below Eagle Point, Oregon. In the event that this data is temporarily unavailable, the permittee may use the historical average adjusted by the relative flows from the nearest available USGS gauging station. In the event the data from either gauging station becomes permanently unavailable, the permittee must obtain DEQ approval for an alternative flow determination strategy.59

Monitoring for UV dose is preferable to monitoring for UV intensity. For more information, refer to Monitoring Matrix on the Permit Writers’ Corner.

60 This note applies to STEP systems only. It was developed by Western Region permitting staff using Best Professional Judgment. The reason DEQ has decided to assume that influent BOD5 and TSS concentrations are 200 mg/L is that the municipalities that have such systems are typically very small, and have limited ability to establish performance-based limits.

61 DEQ does not require that WET tests be conducted at the same time as other required monitoring; however it should be emphasized to the permittee that apart from the upfront cost, there are advantages to doing so. These include potentially reduced costs of followup investigations if the WET test results indicate toxicity.

62 The type of sample (grab or composite) is dependent on the type of facility, discharge and pollutants of concern. Grab samples are appropriate for smaller facilities that may not have a composite sampler. Grab samples are also appropriate for intermittent discharges and for discharges where the pollutants of concern include volatiles.



65 The following contains information on what is involved in calibrating different types of meters: https://www.us-br.gov/tsc/techreferences/mands/wmm/WMM_3rd_2001.pdf

66 Other monitoring parameters may be added as necessary for a particular facility. This should be determined based on the screening information provided with the permit application, sources of wastewater collected, and the end use (as necessary to protect public health, the environment, and continued agricultural productivity of soils).

https://www.usbr.gov/tsc/techreferences/mands/wmm/WMM_3rd_2001.pdf

68 See OAR 340-050-0035(2)(a).

69 See OAR 340-050-0035(2)(a). Note that though some older permits require monitoring for Ag and Cr, the OAR does not require this. It does however require monitoring for Mo.

70 Language stating that reports must be in a DEQ-approved format is intended to allow DEQ to specify a format without having to modify the permit.71 Though DEQ has not been requiring electronic versions in the past and DOJ says we can start requiring electronic reporting (with a significant grace period) even if the permit does not specify that reports be submitted electronically. 72 DEQ’s Biosolids and Water Resuse Coordinator is developing a standard reporting form. Contact at (503) 229-5472 for details.

73 The date and number of recycled water annual reports to be submitted is specified in the Recycled Water IMD section3.4.4, page 42.

74 Wastewater solids differ from biosolids in that they have not yet undergone treatment.

75 Wastewater solids report provides metrics on use/disposal for facilities and data for compliance/technical assistance. A reporting form will be developed with the biosolids annual report.

76 No date is given in rule. This date was selected to coordinate with the biosolids annual report.

77 The February 19th date is specified in OAR 340-050-0035(6) and 40 CFR §503.18.

78 A Class I sludge management facility is any publicly-owned treatment works (POTW) required to have an approved pretreatment program. The CFR language is as follows: 40CFR§503.9(c) Class I sludge management facility is any publicly owned treatment works (POTW), as defined in 40 CFR 501.2, required to have an approved pretreatment program under 40 CFR 403.8(a) (including any POTW located in a State that has elected to assume local program responsibilities pursuant to 40 CFR 403.10(e)) and any treatment works treating domestic sewage, as defined in 40 CFR 122.2, classified as a Class I sludge management facility by the EPA Regional Administrator, or, in the case of approved State programs, the Regional Administrator in conjunction with the State Director, because of the potential for its sewage sludge use or disposal practice to affect public health and the environment adversely.

79 This date is not in rule and is negotiable.

80

For more information on the development of compliance schedules, see DEQ’s compliance schedule IMD. This IMD may be found at: http://www.deq.state.or.us/wq/pubs/imds/ComplianceSchedule.pdf

81 This language must be included in the permit as per the Compliance Schedule IMD. This IMD may be found at: http://www.deq.state.or.us/wq/pubs/imds/ComplianceSchedule.pdf

82 Though the OAR does not specifically require that all facilities have an I/I program or that they submit an annual report, including such requirements in the permit will help municipalities maintain the investment of public funds that their collection system represents. These requirements may be waived in the case of small commercial facilities that don’t really have collection systems or that have no evidence of I/I.

88 OAR 340-050 requires a land application plan regardless of the Class of biosolids. However, since the land application of Class A biosolids are not subject to the same conditions as Class B biosolids, the land application plan may not require the same level of detail. In any case, Class A facilities may want to maintain a land application plan that allows them the option of land applying Class B biosolids. See the Biosolids IMD for more information.

89 See 40CFR122.21(q)(9)(v)(D).

90 See OAR 340-050-0030(1).

91 See OAR 340-050-0030(2).

92 OAR 340-050-0031(1) requires only 60 days, however, this time frame is generally too short to meet.

93 It is preferred that the West Coast species are tested if possible, but there may be some difficulty in getting some of the organisms especially the west coast mysids. As always test organisms should be chosen based on potential toxicants & areas of concern, ie. If the discharge is into a shellfishing area, it is recommended that a mussel or oyster test be conducted for the invertebrate instead of the mysids. For more information, contact DEQ WET test specialist Lori Pillsbury.

94 See OAR 340-049-0010(17).

95 The term “designated operator” is included to provide clarity for operators who may otherwise interpret “supervisor” to be the person within their organization that they report to, such as the city manager.

96See OAR 340-049-0010(18). 97 See OAR 340-049-0010(16).

103 See OAR 340-049-0015(8).

104 The permit writer should discuss the timing of this evaluation with the permittee. The evaluation should be completed at least once per permit cycle.

105 The content and format of this report must follow the most recent version of DEQ’s Guidance For Completing Oregon DEQ Pretreatment Annual Report Forms. (http://www.deq.state.or.us/wq/pretreatment/docs/guidance/annual-rptguide.pdf)
