HomeMy WebLinkAboutNC0026921_Fact Sheet_20200108DENR/DWQ EXPEDITED FACT SHEET - NPDES PERMIT DEVELOPMENT NPDES Permit: NCO026921 2019 Renewal This form must be completed by Permit Writers for all expedited permits which do not require full Fact Sheets. Expedited permits are generally simple 100% domestics (e.g., schools, mobile home parks, etc) that can be administratively renewed with minor changes, but can include facilities with more complex issues (Special Conditions, 303(d) listed water, toxicity testing, instream monitoring, compliance concerns). Facility Information Applicant/Facility Name: Town of Parkton / Parkton WWTP Applicant Address: PO Box 55; Parkton, NC 28371 Facility Address: 240 Sewer Plant Road (NCSR 1724), Parkton, NC Facility Class/Permit Status: Grade II Biological WPCS / Renewal Permitted Flow 0.20 MGD Type of Waste 100% Domestic Receiving Stream Dunns Marsh Stream Classification C-Swamp Subbasin 03-07-53 USGS Topo Hope Mills County Robeson Regional Office FRO Basic Information for Expedited Permit Renewal Permit Writer / Date Bradley Bennett / 08-04-2019 Does permit need daily max NH3 limits? Already included in existing permit Does permit need TRC limits/language? Already included in existing permit Does permit have toxicity testing? Yes, see discussion below. Does permit have Special Conditions? Yes, sediment monitoring for mercury and mercury reopener clause Does permit have instream monitoring? Yes, DO and Temp.; see discussion below Stream on 303(d) List? For w/parameter? TMDL for Fish Tissue Mercury — 14-22-1-3-2 Any compliance concerns? See compliance discussion below Any modifications since last permit? None noted in the current application New expiration date: July 31, 2024 FACILITY OVERVIEW: This facility supports no industry and has no pretreatment program. The existing activated -sludge treatment system consists of - Automatic bar screen, grit removal, influent splitter box • two oxidation ditches (operated as parallel treatment trains) • two clarifiers • two sludge recirculation and waste pumping stations • Parshall flume and flow meter • chlorination / dechloringation • step-down post -aeration • aerated sludge digester • sludge drying beds No modifications were noted or proposed in the current application. COMPLIANCE: The facility had one civil penalty assessment action for TSS violations during the recent permit term with a total assessment amount of $1,128.28. The penalty amount of $1,000 was remitted after the permitee showed that the data value was actually reported inaccurately and there was not actually a violation. The facility has had 2 NODS (TRC and frequency) and eleven (11) NOVs covering flow issues and TSS issues in addition to late reporting and bypass. The facility has had two failed toxicity tests in 2018. Submitted data over the permit cycle show 53 months with noted violations, with most of these not accessed due to BPJ determinations (ex. TRC and flooding issues). MERCURY MONITORING: Current Requirement: Quarterly monitoring only, no limit Final Requirement: Once/Term monitoring The applicant has requested that monitoring be changed from quarterly to once per term in line with DWR TMDL Permitting Strategy. They note that all flow is domestic/commercial with no contributions of Hg. Facility monitoring data from 2015 through April 2019 show 16 monitoring events with all results showing detection of Hg with an average of 3.86 and max value of 11.4ng/L. None of the individual values is above 12ng/L. Using the Mercury Evaluation spreadsheet, the results indicate no limit and no management plan required. Internal discussions indicate that there continues to be remaining concern about mercury levels in the Lumber River Basin. The facility has continued to have mercury detection at all sampling events so it is reasonable to continue to monitor for this parameter. No change was proposed in the draft permit. During the final review process Division staff re-evaluated this issue. Consistent with the Division's Mercury TMDL Implementation Strategy it was determined that this facility should be moved to once/term monitoring. Monitoring values never exceeded 12 or 47 evaluation levels in the strategy. Final permit includes Once/Term monitoring and removed the mercury reopener clause. TOXICITY TESTING: Current Requirement: Quarterly testing required for discharge under zero -flow condition, Chronic P/F @ 90 %. No changes recommended. The applicant has asked for removal of this monitoring requirement based on a Division memorandum that generally associates toxicity testing with major facilities or ones discharging complex wastewaters. Under 15A NCAC 0213.0508 the Director can apply toxicity testing to other discharges as deemed necessary. The facility has failed the toxicity test two times (both in 2018) during the permit cycle. The FRO has indicated that because the facility monitors and is limited for NH3 they would be open to removing the WET monitoring requirement. Data for NH3 show no monthly or weekly violations but there were two WET test failures. There do not appear to be efforts to attempt to determine the cause of the toxicity failures. Maintain the WET test requirements in the permit. INSTREAM MONITORING: Town of Parkton WWTP Fact Sheet NPDES Renewal 2019 Page 2 Current Requirement: Upstream and Downstream monitoring for dissolved oxygen (DO) and temperature required weekly. The applicant has requested that these requirements be removed from the permit. The applicant indicated they felt the stream DO was more impacted by agriculture, rain, etc. than their discharge and that their lack of industrial discharges leads to no potential impacts from a temperature standpoint. These parameters are required in 2B .0508 but the requirements may be modified or waived if it is adequately demonstrated that the parameters aren't needed. Data during the permit term show little difference in the U/D and E temperature values. Values show appropriate variability from winter to summer. Over 60% of the U and D DO data are less than 5 mg/L and 50% less than 4, but none of the effluent data is below 6 mg/l. It doesn't appear that the discharge is impacting the DO levels. U/D Temperature and DO monitoring is proposed to be removed from the permit. Effluent monitoring for both parameters will remain at the previous frequencies. CONDUCTIVITY MONITORING: Current Requirement: Effluent monitoring for Conductivity required weekly. The applicant requested removal of conductivity monitoring and argues that the results are consistently within the range of domestic wastewater and that other monitored parameters are sufficient to assess the discharge characteristics. Data values from 2014 to April 2019 show conductivity levels between 102 and 970 with an average of 268.48 umhos/cm. Review of an old EPA document indicated that streams with good mixed fisheries were between 150 and 500 umhos/cm. No other information about conductivity levels was available in our guidance/policies. The monitoring data showed 90% of values were within this range. The regional office staff indicated the wastewater was domestic only and they were unsure why conductivity was in previous versions of the permit. The 1999 Instream Monitoring Policy for 100% domestic indicates no fecal or conductivity monitoring requirements are recommended unless the stream is 303(d) listed for fecal coliform bacteria. This facility does not discharge to stream segment listed for fecal bacteria. Conductivity monitoring has been removed from the draft permit. SPECIAL CONDITION — SLUDGE MONITORING REQUIREMENT: Current Requirement: Sludge biosolids tested 2/year for Hg. The applicant requested removal of this requirement indicating that there is no environmental impact since the sludge is dewatered and taken to the landfill. They indicated that they may not even produce sludge for years so they may not be able to meet the permit conditions to monitor 2/yr. As noted above, all sixteen effluent monitoring events for Hg show detection. Given this result, it seems inappropriate to remove the sludge monitoring requirement. To address the concern for monitoring when no sludge is generated, language has been added to the permit to require that the permitee submit a letter to the DWR when monitoring is not performed due to a lack of sludge material to monitor. This will satisfy the requirement in the permit. PROPOSED PERMIT CHANGES: Town of Parkton WWTP Fact Sheet NPDES Renewal 2019 Page 3 • Updated eDMR requirements • Added regulatory citations throughout permit • Updated parameter codes • Removed U/D temperature and DO monitoring requirements. • Removed Conductivity monitoring. • Added language to require permittee to submit a letter to DWR when sludge material is not generated and monitoring is not possible.

From: Bennett, Bradley Sent: Wednesday, August 28, 2019 10:57 AM To: Brantley, Mark<mark.brantley(@ncdenr.gov> Subject: Questions on Permit Renewals Hey Mark, The Electronic Signature stuff and a couple of other projects have eaten more time than I thought. I'm finally getting back on the renewals. I just wanted to run a couple of things by you before I finalized the draft on these two. Let me know your thoughts on these and I can get them ready to go to notice. • Parkton — they asked for a number of changes. See below and how I'm planning to respond. o They asked to change mercury monitoring from quarterly to once/term in line with the DWR TMDL. All of their quarterly results have had detect for mercury avg 3.86ng/L and high of 11.4. None are above 12 and the spreadsheet results don't lead to a limit but we are thinking that because of the continued concern in this basin and the fact that they continue to have mercury detected we are going to maintain the quarterly requirement. o They asked to have their WET requirement removed since they aren't a major, etc. They have failed tox twice — both in 2018. We had discussed that they had the ammonia limits and that might be sufficient in lieu of tox. However, since they have the two failures and there has been no indication they have tried to evaluate the cause, we plan to maintain the WET requirement. What are your thoughts on this? I could mention in their cover letter or add language to the permit about the need to evaluate the cause of the failures for future consideration? o They asked for removal of U/D monitoring for DO and temperature. The data for the permit cycle show 60% of the U and D values are less than 5mg/L but none of the effluent data values are below 6mg/L. So it doesn't seem their discharge is impacting the DO levels instream. For temperature the U and D values are very consistent over the cycle and show expected fluctuations with season. We are proposing the accept their request here and remove U/D DO and Temp. they will continue to monitor both DO and Temp at the Effluent. o They asked to have effluent Conductivity monitoring removed. Data is all between 102 and 970 with an average of around 268 umhos/cm. 90% of the values are between 150 and 500 which seems to be consistent with reasonable values. We don't really have too much in the policy area to gauge what to do with this, but since the wastewater is all domestic and the values seem in line we are proposing the remove Conductivity. Any concerns? o They asked to have their sludge monitoring for Hg — 2/yr — removed. Given the discussion above on Hg this will remain in the permit. They did indicate that they often don't produce sludge so they couldn't meet the required 2/yr monitoring. They obviously don't understand they can just send a letter indicating this. We will add some language about this in the permit. • St. Pauls — o They only asked for removal of Conductivity. This is monitored weekly at the effluent. The data (226 data points) range from 175 to 3,012umhos/cm. That high one is an outlier, if you take it out the avg is around 306. Over 98% of the values are between 175 and 500. The only real stretch above 400 is Sept 2017 through Sept 2018? Any concerns about accepting this request and removing Conductivity? o Flow is obviously the big issue with these guys and they are already under SOC so we can let that process deal with this issue. o Ammonia N — in the permit their winter monitoring shows as 2/month. From the data it looks like they have been sampling monthly. In a previous version of the permit they were just monitoring for NH3-N 2/month with no limit. Then limits were added and the monitoring usually goes to weekly. They seem to have been doing this correctly, we just need to make the change in the permit so both are "Weekly" Thanks Mark!

NC0026921 Parkton WWTP / Town of Parkton FRO Comments / Notes from Application: • Requested change in Hg monitoring from quarterly to once/term in line with DWR TMDL Permitting Strategy. Flow is all domestic/commercial with no contributors of Hg. — Last permit cycle they asked for removal and DWR changed monitoring from monthly to quarterly and removed the limit, but maintained monitoring because the facility had mercury detected on 57 of 57 events and because of "EPA's ongoing concern about mercury at this facility." There is no additional information in the file that outlines any EPA comments on this facility. Possibly this is in another file and is applicable across a basin? — Data from 2015-2018 show sixteen Hg monitoring events and all of these show detection. Average is 3.86 and max is 11.4ng/L. — RPA (if done correctly) shows Max Predicted Cw of 17.3 ng/L. This is above the 12 allowable. None of the individual values is above 12 or the TBEL of 47ng/L. — Using the Mercury Evaluation spreadsheet, the results indicate no limit and no MMP required. — The two spreadsheets are attached. — Options: 1) Require monitoring once per term in line with the strategy. 2) If there is justification for EPA's and DWR's continued concern for Hg at this facility then maintain the quarterly monitoring. With this option, need to know what to include in the response as our reasoning for maintaining the current monitoring. Maintained in draft permit — After notice re-evaluated this issue and discussed internally. In keeping with the TMDL Implementation Strategy changed final permit to once/term. Also removed the Mercury Reopener clause. • Requested removal of quarterly WET. Noted online 1999 memo that says required for majors or complex wastewaters and they are neither. — Asked for removal at last renewal but maintained due to failed WET and other compliance issues during the permit cycle. — 2B .0505(d) gives the Director the authority to require monitoring where it is felt that use may be impaired or toxic substances are known or suspected in the discharge. — Failed twice in 2018 and once in 2016. Have passed the last three. — Region may be okay with NH3 monitoring instead of WET. Data (2015-2018) show no violations of monthly or weekly limits for NH3. There is no indication of any efforts to determine the toxicity source for the failed sampling. — Options: Maintain the WET testing due to the three failed events. Do we ever include conditions that allow the permitee to evaluate the potential causes of the failed tests and use that information to reassess the monitoring? If they could somehow show that the cause could in fact be accessed through NH3 monitoring then that change may be appropriate. — The regional office indicated that the permitee had to "feed" the plant because it was a low strength influent. The permitee apparently uses dog food or milk in this process. Not sure if this could impact the WET results? • Requested removal of U/D monitoring for Temp and DO. They indicated they felt the stream DO was more effected by agriculture, rain, etc. than their discharge. Temp — no industrial discharges that could impact temp. — These parameters are required in 213.0508. The requirements may be modified or waived under 2B .0508(b)(1) if demonstrated to the Director's satisfaction that requirements aren't needed. 1999 instream policy delegated to NPDES Supervisor to add or delete any instream monitoring for 100% domestic dischargers. — Data during the last permit cycle seem to show very little difference between the U/D and E temperature values. These values show appropriate variability between winter and summer months and appear to be reasonable numbers. — The Effluent DO data show no values less than 6mg/L, but the Upstream and Downstream data show that 61% (125 of 206) of Upstream and 64% (132 of 206) of Downstream values are less than 5mg/L. Looking at the DMR data charts from BIMS the DO values appear relatively consistent upstream and downstream and these values are fairly low compared to the effluent DO. U/D values are often (50%) less than 4mg/L. It would not seem that the discharge is impacting already depressed DO levels. — Options: Remove U/D for Temp and DO? Requested removal of Conductivity monitoring. Applicant argues that results are consistently within the range of domestic WW and that other parameters are sufficient to assess effluent. — Asked for this also in last renewal. No information in 2014 renewal file about decision to maintain. — Data values over the permit cycle were from 102 to 970 with an average of 268.48. Old EPA document said streams with good mixed fisheries were between 150 & 500 micromhos/cm. I could not find any other information about conductivity levels for evaluation in our policies, etc. The data evaluated indicate that 90% (198 of 218 values) were within this range. — Regional office staff was unsure why conductivity was in the permit indicating that the wastewater was domestic only. — Option: Remove Conductivity monitoring requirement. 1999 instream monitoring policy for 100% domestic indicates no fecal or conductivity monitoring unless stream is 303(d) listed for fecal coliform bacteria. • Requested that the Sludge Monitoring requirement (Hg) be removed. They have to test biosolids 2/yr for Hg. They state there is no environmental impact since sludge is dewatered and taken to landfill. They indicated that they may not produce sludge for years so they can't meet the requirement. Permitee asked for this in last renewal also, denied due to ongoing effluent detection of Hg. — All sixteen monitoring points for permit cycle showed Hg detection. — Option: Maintain the requirement in the permit but add clarifying language that they if they do not produce sludge then they would just need to provide a letter indicating this to us. — If Hg dropped to once per term would this remain? Also, the condition required result to be submitted with DMR? How do we handle with electronic? Is there a way to report in eDMR? • Note secured AIA (Asset and Inventory Assessment) grant to evaluate sewer collection system. Compliance / Enforcement: • 53 months with violations noted in BIMS — most of these are not assessed due to BPJ (ex TRC and flooding issues) • NOD's 2015 (TRC) and 2019 (monitoring frequency) • 11 NOV's over permit term, mainly flow early in cycle, also TSS, Conductivity (Frequency), late reporting and bypass. • Enforcements — one in 2018 for 2017 limits violations for TSS. Permitee assessed Approx. $1,200 but the civil penalty of $1,000 was remitted when the permitee showed that the DMR was reported inaccurately as 608 instead of 6.8. • 2 Bypasses in 2015 • Failed Tox twice in 2018 and once in 2016. Passed last three tests. Discussion with FRO (Mark Brantley 5/8/19): • Hg — not sure why this is in the permit, check strategy. • Toxicity — permit has ammonia limit so may be open to having this v/s tox? • Conductivity — unsure why it is in the permit, waste is all domestic • Sludge issue — facility just needs to send in a letter if there is no sludge • Plant has weak influent and they have to feed it (dog food or milk) to make it work. No food coming in, low strength ww.

The permit expiration date is July 31, 2019. The permit application package consists of: - Cover letter - One original of Form 2A — NPDES Application for Permit Renewal, Parts: A, B, C and E - Topographic Map - Process Flow Schematic and Narrative - Two additional copies of Renewal Package The Town would like to request the following changes to the permit: • The permit currently contains a quarterly monitoring requirement for mercury. We are requesting that the monitoring be changed to reflect the monitoring requirements per the NC DWR Mercury Post-TMDL Permitting Strategy (September 12, 2012). Based on our understanding of the strategy, as a minor municipal facility, we should only have to monitor once every five years. The wastewater flow to the plant is entirely domestic/commercial with no known contributors of mercury, such as dental offices. • The Town requests that quarterly monitoring for Chronic Toxicity be removed from the permit. In your online guidance, there is an August 2, 1999 memorandum that states that toxicity testing will be required at "major" facilities or those facilities discharging "complex" wastewaters. The flow to the WWTP is a combination of domestic discharges from residential and commercial sources with no industrial contributions and should not be subject to the toxicity requirement. • It is requested that the upstream and downstream monitoring requirements for Dissolved Oxygen and Temperature be removed from the permit. The receiving stream flows through swampland/woodland that is bordered by farmland. The testing of DO and Temperature at the two monitoring sites has no correlation to the discharge from the wastewater plant. DO in the stream is more likely to be affected by agricultural runoff, natural decay, rainfall, etc. and any increase or decrease in DO cannot be definitely attributed to the treatment plant. Again, since the wastewater flow is domestic in nature with no industrial dischargers that could potentially discharge high temperature waste it is improbable that the discharge will affect stream temperature. It is requested that conductivity monitoring be removed from the permit. A review of test results shows that the conductivity of the effluent is consistently in the range for domestic wastewater. As the wastewater is purely domestic, any changes in the conductance of the water would be attributable either to temperature or potable water characteristics. Current permit required testing for BOD5, TSS, and NH3 are sufficient to determine effluent clarity. We request that condition A. (3.) Sludge Monitoring Requirements be removed from the permit. This requires the Town to test the biosolids twice per year for mercury. Any waste sludge generated by the WWTP is dewatered on the sand drying beds and then taken to a landfill for final disposal. The presence or absence of mercury in the biosolids can have no environmental impacts. Secondly, due to the low influent BOD5, the plant may not produce waste sludge for years at a time. With no waste sludge, the Town could not meet this requirement. We appreciate your consideration of these requests. If you have any questions or comments, please contact Roy Lowder, WWTP Operator in Responsible Charge, at 910-975-4715. Sincerely, AI McMillan, Mayor Town of Parkton Town of Parkton WWTP Treatment Plant Narrative NPDES NCO026921 The Town of Parkton WWTP consists of the following units: • Barscreen • Two parallel operating oxidation ditches • Two parallel operating secondary clarifiers • Two sludge recirculation and waste pump stations • Parshall flume and flow meter • Chlorine contact basin • Post aeration • Aerobic sludge digester • Sludge drying beds The Parkton WWTP is an activated sludge system using oxidation ditches for aeration and conventional clarifiers for sedimentation. Each clarifier is equipped with a sludge pumping station which can be used to recycle the activated sludge to the aeration process or waste the sludge to the aerobic digester. Effluent from the activated sludge process is disinfected in the chlorine contact basin and then dechlorinated. After disinfection, post aeration is accomplished by cascade steps to insure maintenance of minimum dissolved oxygen levels.
