RENEWAL Pursuant to the provisions of the Federal Water Pollution Control Act, Title 33 USC, Section 1251, et. seq. and Conditions of Licenses, 38 M.R.S.A., Section 414-A et seq., and applicable regulations, the Department of Environmental Protection (Department hereinafter) has considered the application of the PENOBSCOT INDIAN NATION (PIN/permittee hereinafter) with its supportive data, agency review comments, and other related material on file and FINDS THE FOLLOWING FACTS:
APPLICATION SUMMARY The PIN has submitted an application to the U.S. Environmental Protection Agency (EPA) to renew National Pollutant Discharge Elimination System (NPDES) permit #ME0101311 issued by the EPA on January 26, 2006, for a five-year term. The NPDES permit approved the discharge of up to a monthly average flow of 0.10 MGD of secondary treated sanitary wastewater from a treatment facility to the Penobscot River, Class B, in Old Town, Maine. On October 16, 2012, the PIN submitted another application to the Department to renew Maine Waste Discharge License (WDL) #W002672-5L-C-R, which was issued by the Department on March 29, 2000, for a five-year term. The WDL approved the discharge of up to a monthly average flow of 0.07 MGD of secondary treated sanitary wastewater from a treatment facility to the Penobscot River, Class B, in Old Town, Maine.
PERMT SUMMARY This permitting action is carrying forward all the terms and conditions of the previous permitting action with the following exceptions: 1) Eliminating the seasonal monitoring requirements for total phosphorus and ortho-phosphorus as the Department has made a best professional judgment it has enough information of the quantity of total phosphorus and ortho-phosphorus discharged and determined the impact on the receiving water is de mininds.ME0101311 PERMIT Page 2 of 10

W002672-6B-D-R PERMT SUMMARY (c ont'd) 2) Increasing the technology based mass limitations for biochemical oxygen demand (BOD) and total suspended solids (TSS) to correct an error in the previous permitting action. 3) Reducing the monitoring frequency for BOD, TSS, settleable solids and E. coil bacteria based on a statistical analysis of the compliance data for the previous four-year period. 4) Incorporating mercury limitations into this permit that were originally established in a license modification issued by the Department on May 23, 2000.
CONCLUSIONS BASED on the findings in the attached Fact Sheet dated October 24, 2012, and subject to the Conditions listed below, the Department makes the following CONCLUSIONS:
1. The discharge, either by itself or in combination with other discharges, will not lower the quality of any classified body of water below such classification.
2. The discharge, either by itself or in combination with other discharges, will not lower the quality of any unclassified body of water below the classification which the Department expects to adopt in accordance with state law.
3. The provisions of the State's antidegradation policy, 38 MRSA Section 464(4)(F), will be met, in that: (a) Existing in-stream water uses and the level of water quality necessary to protect and maintain those existing uses will be maintained and protected; (b) Where high quality waters of the State constitute an outstanding natural resource, that water quality will be maintained and protected; (c) The standards of classification of the receiving water body are met or, where the standards of classification of the receiving water body are not met, the discharge will not cause or contribute to the failure of the water body to meet the standards of classification; (d) Where the actual quality of any classified receiving water body exceeds the minimum standards of the next highest classification, that higher water quality will be maintained and protected; and (e) Where a discharge will result in lowering the existing quality of any water body, the Department has made the finding, following opportunity for public participation, that this action is necessary to achieve important economic or social benefits to the State.ME0101311 PERMIT Page 3 of 10

W002672-6B-D-R CONCLUSIONS (cont'd)
4. The discharge will be subject to effluent limitations that require application of best practicable treatment. 5.

1. APPLICATION SUMMARY a. Application: The Penobscot Indian Nation (PIN) has submitted an application to the U.S. Environmental Protection Agency (EPA) to renew National Pollutant Discharge Elimination System (NPDES) permit #ME0101311 issued by the EPA on January 26, 2006, for a five-year term. The NPDES permit approved the discharge of up to a monthly average flow of 0.10 MGD of secondary treated sanitary wastewater from a municipal treatment facility to the Penobscot River, Class B, in Old Town, Maine. On October 16, 2012, the PIN submitted another application to the Department to renew Maine Waste Discharge License (WDL) #W002672-5L-C-R, which was issued by the Department on March 29, 2000, for a five-year term. The WDL approved the discharge of up to a monthly average flow of 0.07 MGD of secondary treated sanitary wastewater from a municipal treatment facility to the Penobscot River, Class B, in Old Town, Maine. See Attachment A of this Fact Sheet for a location map.ME0101311 FACT SHEET Page 2 of 17

W002672-6B-D-R
1. APPLICATION SUMMARY
b. Source Description: The facility receives commercial and residential sanitary wastewater serving a population of 550 residents on Indian Island in Old Town, Maine. There are no significant industrial users within the collection system and there are no combined sewer overflows. The facility is not authorized to treat transported wastes at the waste water treatment facility.

c. Waste Water Treatment: Sanitary wastewater received at the PIN waste water treatment facility receives a secondary level of treatment. Waste waters generated on Indian Island are conveyed to the treatment facility via a sewer collection system that is primarily a gravity system that is approximately five (5) miles in length with seven (7) pump stations. Five of the seven pump stations have on-site back-up power and the other two pump stations are served by a mobile generator in the event of a power failure. Wastewaters from the collection system are conveyed to the facility headworks where influent screening is performed either through a comminutor or a manual bar rack, followed by an anoxic selector basin for filiaments control. Waste water then flows to a 68,800-gallon oxidation ditch with diffused air, followed by two 27,000 gal circular final clarifiers, the chlorine contact tank where it is seasonally disinfected and then is discharged to Penobscot River via a 10" diameter pipe. The outfall pipe extends out into the receiving water approximately 75 feet with approximately 10 feet of water over the crown of the pipe at normal low water levels. The end of the outfall pipe is not fitted with a diffuser to enhance mixing with the receiving waters, Between May 1 and October 31 of each year, the effluent is disinfected with sodium hypochlorite. Flow is measured by a continuous recording flow meter. Sludge is wasted from the clarifiers to two 8,000 gal. aerobic digesters and can be then pumped to a belt filter press for dewatering. Sludge can be also stored in the digestors which are former package processing units. Sludge is then disposed of at the Old Town Compost Facility, a Department approved site.
2. PERMIT SUMMARY a. Terms and conditions: This permitting action is carrying forward all the terms and conditions of the previous permitting action with the following exceptions: 1) Eliminating the seasonal monitoring requirements for total phosphorus and orthophosphorus as the Department has made a best professional judgment it has enough information of the quantity of total phosphorus and ortho-phosphorus discharged and determined the impact on the receiving water is de minimis. 2) Increasing the technology based mass limitations for biochemical oxygen demand (BOD) and total suspended solids (TSS) to correct an error in the previous permitting action.ME0101311 FACT SHEET Page 3 of 17

W002672-6B-D-R 2. PERMIT SUMMARY (cont'd) 3) Reducing the monitoring frequency for BOD, TSS, settleable solids and E. coil bacteria based on a statistical analysis of compliance data for the previous four-year period. 4) Incorporating mercury limitations into this permit that were originally established in a license modification issued by the Department on May 23, 2000, b. History: The most relevant licensing/permitting actions include the following: November• 21, 1988 - The U.S. Environmental Protection Agency (EPA) issued National Pollutant Discharge Elimination System (NPDES) permit #ME0101311 to the PIN for a five-year term. June 22, 1988 - The Department issued WDL #W002672-59-B-R to the PIN for a fiveyear term. March 29, 2000 - The Department issued WDL #W002672-5L-C-R to the PIN for a fiveyear term. May 23, 2000 — The Department issued a modification of the 3/29/00 WDL by establishing interim average and maximum concentration limits for total mercury along with a 2/Year monitoring requirement. January 26, 2006 - The EPA issued NPDES peintit #ME0101311 to the PIN for a fiveyear term. October 21, 2010 — The PIN submitted an application to the EPA for the renewal of NPDES permit. EPA deemed the application incomplete and requested additional information. February 15, 2011 — The EPA deemed the PIN application complete for processing after the PIN submitted the additional information requested by the EPA. October 5, 2012 — The Department received the PIN's NPDES application from the EPA.

W002672-6B-D-R
3. CONDITIONS OF PERMITS Maine law, 38 M.RS.A. Section 414-A, requires that the effluent limitations prescribed for discharges, including, but not limited to, effluent toxicity, require application of best practicable treatment (BPT), be consistent with the U.S. Clean Water Act, and ensure that the receiving waters attain the State water quality standards as described in Maine's Surface Water Classification System. In addition, 38 M.R.S.A., Section 420 and Department rule 06-096 CMR Chapter 530, Surface Water Toxics Control Program, require the regulation of toxic substances not to exceed levels set forth in Department rule 06-096 CMR Chapter 584, Surface Water Quality Criteria for Toxic Pollutants, and that ensure safe levels for the discharge of toxic pollutants such that existing and designated uses of surface waters are maintained and protected.
4. RECEIVING WATER QUALITY STANDARDS Maine law, 38 M.R.S.A., Section 467(7)(A)(6) indicates the Penobscot River main stem, from the Maine Central Railroad bridge in Bangor to a line extended in an east-west direction from the confluence of Reeds Brook in Hampden, is classified as a Class B waterway. The Legislature finds that the free-flowing habitat of this river segment provides irreplaceable social and economic benefits and that this use must be maintained. Maine law, 38 M.R.S.A., Section 465(3) describes standards for classification of Class B waters as follows: Class B waters must be of such quality that they are suitable for the designated uses of drinking water supply after treatment; fishing; agriculture; recreation in and on the water; industrial process and cooling water supply; hydroelectric power generation, except as prohibited under Title 12, section 403; navigation; and as habitat for fish and other aquatic life. The habitat must be characterized as unimpaired. The dissolved oxygen content of Class B waters may not be less than 7 parts per million or 75% of saturation, whichever is higher, except that for the period from October 1st to May 14th, in order to ensure spawning and egg incubation of indigenous fish species, the 7-day mean dissolved oxygen concentration may not be less than 9.5 parts per million and the 1-day minimum dissolved oxygen concentration may not be less than 8.0 parts per million in identified fish spawning areas. Between May 15th and September 30th, the number of Escherichia coli bacteria of human and domestic animal origin in these waters may not exceed a geometric mean of 64 per 100 milliliters or an instantaneous level of 236 per 100 milliliters. In determining human and domestic animal origin, the department shall assess licensed and unlicensed sources using available diagnostic procedures. Discharges to Class B waters may not cause adverse impact to aquatic life in that the receiving waters must be of sufficient quality to support all aquatic species indigenous to the receiving water without detrimental changes in the resident biological community.ME0101311 FACT SHEET Page 5 of 17

5. RECEIVING WATER CONDITIONS Table Category 5-D entitled, Rivers and Streams Impaired By Legacy Pollutants, in a document entitled, 2010 Maine Integrated Water Quality Report, [referred to as the "305(b) Report"] published by the Department states the designated use of fishing (consumption) is impaired in a 14-mile segment of the Penobscot River in the vicinity of the permittee's outfall due to the presence of PCBs in fish tissue. The Department is not aware of any information that indicates the discharge from the permittee is causing or contributing to the impairment. In addition, the 305b Report lists all freshwaters in Maine in Category 4-A: Rivers and Streams With Impaired Use, TMDL Completed. Impairment in this context refers to the designated use of recreational fishing due to elevated levels of mercury in some fish caused by atmospheric deposition. As a result, the State has established a fish consumption advisory for all freshwaters in Maine. The Report states that a regional scale TMDL has been approved. In addition, pursuant to Maine law, 38 M.R.S.A. §420(1-B)(B), "a facility is not in violation of the ambient criteria for mercury if the facility is in compliance with an interim discharge limit established by the Department pursuant to section 413 subsection 11." The Department has established interim monthly average and daily maximum mercury concentration limits for this facility. See the discussion on compliance in section 6(i) of this Fact Sheet. In the summers of 1997, 2001 and 2007, the Department conducted ambient water quality sampling on a 103-mile segment of the Penobscot River from Millinocket to Bucksport. Reports entitled, Penobscot River Modeling Report, Final, June 2000, Penobscot River Data Report May 2002, and Penobscot River Modeling Report Draft, March 2003, prepared by the Department, indicate there are sections of non-attainment of dissolved oxygen standards as a result of algal blooms in portions of the Class B sections of the rivers. These sections of river have experienced measured DO non-attainment at various locations during periods of low flow and high water temperature. Measured DO non-attainment is predominantly in the early morning hours in sections of river with significant diurnal dissolved oxygen (DO) swings. These significant diurnal DO swings are caused by nutrient enrichment and resulting plant growth. The Department has issued a report entitled, Penobscot River Phosphorus Waste Load Allocation, May 2011 stating seasonal mass based total phosphorus limitations are necessary for the four industrial dischargers on the river as well as monitoring for total phosphorus for five municipal waste water treatment facilities. The PIN facility was not named as a facility required to monitor for phosphorus. The specific eutrophication related responses that are targeted by the waste load allocation are not expected to persist into the tidally influenced portion of the Penobscot River. However, water quality improvements associated with the waste load allocation are expected to extend into the tidally influenced section of the river. The effectiveness of the nutrient load reductions will be assessed through routine ambient monitoring for total phosphorous, dissolved oxygen and biochemical oxygen demand.ME0101311 FACT SHEET Page 6 of 17

W002672-6B-D-R
5. RECEIVING WATER CONDITIONS (cont'd) If ambient water quality monitoring or future modeling determines that at full permitted discharge limits the permittee's discharge is causing or contributing to the non-attainment of standards, this permit will be re-opened per Special Condition K, Reopening of Permit For Modifications, to impose more stringent limitations to meet water quality standards.
6. EFFLUENT LIMITATIONS & MONITORING REQUIREMENTS

a. Flow: The previous permit established a monthly average flow limitation of 0.100 MGD and a daily maximum reporting requirement that are being carried forward in this permitting action and is considered to be representative of the monthly average design flow for the facility. A review of the monthly Discharge Monitoring Report (DMR) data for the period January 2009 — July 2012 indicates the permittee has reported values as follows: Flow (DMRs=43 Value Limit (MGD) Range (MGD) Mean (MGD) Monthly average 0.100 0.041 — 0.094 0.057 Daily maximum Report 0.065 — 0.172 0.093
b. Dilution Factors: Dilution factors associated with the discharge from the PIN waste water treatment facility were derived in accordance with freshwater protocols established in Department Regulation Chapter 530, Surface Water Toxics Control Program, November 2005. With a monthly average treatment plant design flow of 0.100 MGD, dilution calculations are as follows: Acute: 1Q10 = 2,660 cfs (1) (2,660 cfs)(0.6464) + 0.100 MGD = 17,195:1 0.100 MGD Modified Acute: '/4 1Q10 = 665 cfs= (665 cfs)(0.6464) + 0.100 MGD = 4,300:1 0.100 MGD Chronic: 7Q10 = 3,129 cfs (1) (3,129 cfs)(0.6464) + 0.100 MGD = 20,227:1 0.100 MGD Harmonic Mean = 8,313 cfs (2) = (8,313 cfs)(0.6464) + 0.100 MGD =53,736:1

0.100 MGD (1) 7Q10 and 1Q10 critical low flow values were recalculated (lowered) in calendar year 2003 during the Department's update of the water quality model for the Penobscot River. (2) Harmonic mean flow from 1991 study and drainage area ratio.ME0101311 FACT SHEET Page 7 of 17

W002672-6B-D-R 6. EFFLUENT LIMITATIONS & MONITORING REQUIREMENTS (cont'd) c. BOD5 & TSS - The previous permitting established technology based monthly and weekly average BOD5 and TSS best practicable treatment (BPT) concentration limits of 30 mg/L and 45 mg/L respectively, that were based on secondary treatment requirements of the Clean Water Act of 1977 §301(b)(1)(B) as defined in 40 CFR 133.102 and Department rule Chapter 525(3)(111). The maximum daily BOD5 and TSS concentration limits of 50 mg/L were based on a Department best professional judgment of BPT. All three concentration limits are being carried forward in this permitting action. As for mass limitations, the previous permitting action established technology based monthly average and daily maximum limitations based on a monthly average limit of 0.007 MGD that was in error. The permittee submitted an application to the EPA that indicated the dry weather design capacity of the treatment facility was in fact 0.10 MGD and not 0.07 MGD. Therefore, to correct the error in the mass limits for BOD and TSS, the Department has calculated technology based mass limits as follows; Monthly average: (0.100MGD)(8.34)(30 mg/L) = 25 lbs/day Weekly average: (0.100 MGD)(8.34)(45 mg/L) = 38 lbs/day Daily maximum: (0.100 MGD)(8.34)(50 mg/L) = 42 lbsiday A review of the monthly DMR data for the period January 2009 — July 2012 indicates values have been reported as follows;
BOD Mass MRs=43 Value Limit (lbs/day) Range (lbs/day) Average (lbs/day) Monthly Average 25 1.4 — 6.5 3.7 Weekly Average 38 Not reported n/a Daily Maximum 42 2.1 — 9.3 4.7

TSS mass MRs=43 Value Limit (lbs/day) Range (lbs/day) Average (lbs/day) Monthly Average 25 0.3 — 3.8 1.7 Weekly Average 38 Not reported n/a Daily Maximum 42 0.4 — 6,4 2.3 TSS concentration (DMRs=43 Value Limit (mg/L) Range (mg/L) Average (mgfL) Monthly Average 30 0.6 — 11.1 3.2 Weekly Average 45 0.6 — 13.2 4.2 Daily Maximum 50 0.6 — 13.2 4.2 On April 19, 1996, the USEPA issued a guidance document entitled, "Interim Guidance for Performance Based Reductions of NPDES Permit Monitoring Frequencies" (USEPA 1996) as the basis for determining reduced monitoring frequencies. The guidance document was issued to reduce unnecessary reporting while at the same time maintaining a high level of environmental protection for facilities that have a good compliance record and pollutant discharges at levels below permit requirements. Monitoring requirements are not considered effluent limitations under section 402(o) of the Clean Water Act and therefore, anti-backsliding prohibitions would not be triggered by reductions in monitoring frequencies
The EPA Guidance indicates "...the basic premise underlying a performance-based reduction approach is that maintaining a low average discharge relative to the permit limits results in a low probability of the occurrence of a violation for a wide range of sampling frequencies." The monitoring frequency reductions in EPA's guidance were designed to maintain approximately the same level of reported violations as that experienced with the existing baseline sampling frequency in the permit. To establish baseline performance the long term average (LTA) discharge rate for each parameter is calculated using the most recent two-year data set of monthly average effluent data representative of current operating conditions. The LTA/permit limit ratio is calculated and then compared to the matrix in Table I of EPA's guidance to determine the potential monitoring frequency reduction. It is noted Table I of EPA's guidance was derived from a probability table that used an 80% effluent variability or coefficient of variation (cv). The permitting authority can take into consideration further reductions in the monitoring frequencies if the actual cv for the facility is significantly lower than the default 80% utilized by the EPA in Table I. In addition to the parameter-by-parameter performance history via the statistical evaluation cited above, the EPA recommends the permitting authority take into consideration the facility enforcement history and the parameter-by-parameter compliance history and factors specific to the State or facility. If the facility has already been given monitoring reductions due to superior performance, the baseline may be a previous permit.ME0101311 FACT SHEET Page 9 of 17

W002672-6B-D-R 6. EFFLUENT LIMITATIONS & MONITORING REQUIREMENTS (cont'd) Though EPA's 1996 Guidance recommends evaluation of the most current two-years of effluent data for a parameter, however, the Department is considering 43 months of data (January 2009 — July 2012). A review of the monitoring data for BOD and TSS indicates the ratios (expressed in percent) of the long term effluent average to the monthly average limits can be calculated as follows:
BOD Long term average — 3.7 lbs/day Monthly average limit = 25 lbs/day Current monitoring frequency = 2/Month Ratio = 3.7 lbs/day = 15% 25 lbs/day According to Table I of the EPA Guidance, a 2/Month monitoring requirement can be reduced to 1/Quarter. The Department is making a best professional judgment that a monitoring frequency of 1/Quarter is not sufficient to determine on-going compliance at the facility. However, the Department is willing to reduce the monitoring frequency for BOD to 1/Month in this permitting action.
TSS Long term average = 1.7 lbs/day Monthly average limit = 25 lbs/day Current monitoring frequency = 2/Month Ratio = 1.7 lbs/day 7% 25 lbs/day According to Table I of the EPA Guidance, a 2/Month monitoring requirement can be reduced to 1/Quarter. As with BOD, the Department is making a best professional judgment that a monitoring frequency of 1/Quarter is not sufficient to determine on-going compliance at the facility. However, the Department is willing to reduce the monitoring frequency for TSS to 1/Month in this permitting action.ME0101311 FACT SHEET Page 10 of 17

W002672-6B-D-R 6. EFFLUENT LIMITATIONS & MONITORING REQUIREMENTS (cont'd) This permitting action is carrying forward a requirement of 85% removal for BOD and TSS pursuant to Department rule Chapter 525(3)(III)(a&b)(3) except in the circumstances where the influent concentration is less than 200 mg/L. A review of the monthly Discharge Monitoring Report (DMR) data for the period December 2010 through July 2012 indicates values have been reported as follows; BOD % Removal (DMRs=19 Value Limit (%) Range (%) Average (%) Monthly Average 85 90 — 97 94
TSS % Removal MRs=19 Value Limit (%) Range (%) Average (%) Monthly Average 85 89 - 99 95 d. Settleable Solids - The previous permitting action established a technology based daily maximum limit of 0.3 milL and a monitoring frequency of 5/Week. The limit which is being carried forward in his permitting action was based on a Department best professional judgment of BPT and the monitoring frequency was based on Department policy for facilities with a monthly average flow limitation greater than 0.1 MGD but less than 0.5 MGD. A review of the monthly DMR data for the period January 2009 — July 2012 indicates values have been reported as follows; Settleable solids (DMRs=43 Value Limit (ml/L) Range (ml/L) Average (ml/L) Daily Maximum 0.3 <0.1 - <0.1 0.05
SS Long term average = 0.05 milL Monthly average limit = 0.3 ml/L Current monitoring frequency = 5/Week Ratio = 0.05 ml/L =17% 0.3 ml/L According to Table I of the EPA Guidance, a 5/Week monitoring requirement can be reduced to 1/Week. Therefore, this permitting action is reducing the monitoring frequency from 5/Week to 1/Week.ME0101311 FACT SHEET Page 11 of 17

W002672-6B-D-R 6. EFFLUENT LIMITATIONS & MONITORING REQUIREMENTS (cont'd)

e. E. coil bacteria: Maine's Water Classification Program found at 38 M.R.S.A. Article 4-A states that Escherichia ea bacteria (E. Coli) standards apply to freshwaters. Based on Maine law, 38 M.R.S.A., §465(3)(B) which relates to Class B waterways, the previous permitting action established a seasonal water quality based monthly average E. coil bacteria limits of 64 colonies per 100 milliliters (m1)(geometric mean) and a daily maximum (instantaneous) level of 427 colonies per 100 ml from May 15 — September 30. These limits are being carried forward from the previous permitting action. During calendar year 2005, Maine's Legislature approved a new daily maximum water quality standards of 236 colonies/100 ml for water bodies designated as Class B and Class C. The Department has determined that end-of-pipe limitations for the instantaneous concentration standard of 427 colonies/100 mL will be achieved through available dilution of the effluent with the receiving waters and need not be revised in MEPDES permits for facilities with adequate dilution such as is the case with the permittee's facility. The bacteria limits established in this permitting action are seasonal and apply between May 15 and September 30 of each year. The Department reserves the right to impose year-round bacteria limits, if necessary, to protect the health, safety and welfare of the public. A review of the monthly Discharge Monitoring Report (DMR) data for the period May 2009 through July 2012 indicates values have been reported as follows;
E. tali bacteria DMRs=18 Value Limit (col/100 ml) Range (col/100 ml) Mean (col/100 ml) Monthly Average 64 0 —16 3.6 Daily Maximum 427 0-366 33

1 / 1 00 ml = 6% 64 coU100 ml According to Table I of the EPA Guidance, a 2/Month monitoring requirement can be reduced to 1/Quarter. As with BOD and TSS, the Department is making a best professional judgment that a monitoring frequency of 1/Quarter is not sufficient to determine on-going compliance at the facility. However, the Department is willing to reduce the monitoring frequency for E. coil bacteria to 1/Month in this permitting action.ME0101311 FACT SHEET Page 12 of 17

W002672-6B-D-R 6. EFFLUENT LIMITATIONS & MONITORING REQUIREMENTS (cont'd)
f. Total Residual Chlorine: Limits on total residual chlorine (TRC) are specified to ensure attainment of the in-stream water quality criteria for levels of chlorine and that BPT technology is utilized to abate the discharge of chlorine. Permits issued by this Department impose the more stringent of the calculated water quality based or BPT based limits. The previous permitting action established a daily maximum limit of 1.0 mg/L. With dilution factors as determined above, water quality based thresholds for TRC may be calculated as follows: Calculated Acute (A) Chronic (C) A & C Acute Chronic Criterion Criterion Dilution Factors Limit Limit 0.019 mg/L 0.011 mg/L 4,300:1 (A) 82 mg/L 222 mg/L 20,227:1 (C) The Department's BPT limitation of 1.0 mg/I is more stringent than the calculated water quality based limit. Therefore, the BPT limitation of 1.0 mg/1 is being imposed from May 15 — September 30 to correspond to seasonal disinfection requirements. A review of the monthly Discharge Monitoring Report (DMR) data for the period May 2009 through July 2012 indicates values have been reported as follows; Total residual chlorine MRs=18 Value Limit (mg/L) Range (mg/L) Mean (mg/L) Daily Maximum 1.0 0,53 ---1.2 0.91
EPA's Interim Guidance for Performance Based Reductions of NPDES Permit Monitoring Frequencies" (USEPA 1996) states that parameters that show any exceedance of a limit during the monitoring period would not be subject to monitoring reductions. The PIN facility has reported three exceedances of the TRC limit during the specified monitoring period. Therefore, the 1/Day monitoring frequency in the previous permit is being carried forward in this permitting action.

g. 0 1 1— The previous permitting action established a technology based p1-1 range limitation of 6.0 — 9.0 standard units based on Department rule Chapter 525(3)(III)(c).The limit range is considered BPT. The monitoring frequency requirement of 1/Day is being carried forward from the previous permitting action. A review of the DMR data for the period January 2009 through July 2012- indicates the pH range limitation has never been exceeded.ME0101311 FACT SHEET Page 13 of 17

W002672-6B-D-R 6. EFFLUENT LIMITATIONS & MONITORING REQUIREMENTS (cont'd) h. Whole Effluent Toxicity (WET) and priority pollutant testing - Maine law, 38 M.R.S.A., Sections 414-A and 420, prohibit the discharge of effluents containing substances in amounts that would cause the surface waters of the State to contain toxic substances above levels set forth in Federal Water Quality Criteria as established by the USEPA. Department Rules, 06-096 CMR Chapter 530, Surface Water Toxics Control Program, and Chapter 584, Surface Water Quality Criteria for Toxic Pollutants set forth ambient water quality criteria (AWQC) for toxic pollutants and procedures necessary to control levels of toxic pollutants in surface waters. WET monitoring is required to assess and protect against impacts upon water quality and designated uses caused by the aggregate effect of the discharge on specific aquatic organisms. Acute and chronic WET tests are performed on invertebrate and vertebrate species. Priority pollutant and analytical chemistry testing is required to assess the levels of individual toxic pollutants in the discharge, comparing each pollutant to acute, chronic, and human health water quality criteria as established in Chapter 584. Chapter 530 establishes four categories of testing requirements based predominately on the chronic dilution factor. The categories are as follows:
Level I — chronic dilution factor of <20:1. Level II — chronic dilution factor of >20:1 but <100:1, Level III — chronic dilution factor >100:1 but <500:1 or >500:1 and Q >1.0 MGD Level IV — chronic dilution >500:1 and Q <1.0 MGD Department rule Chapter 530 (2)(D) specifies the criteria to be used in determining the minimum monitoring frequency requirements for WET, priority pollutant and analytical chemistry testing. Based on the Chapter 530 criteria, the permittee's facility falls into the Level IV frequency category as the facility has a chronic dilution factor >500:1 and discharges <1.0 MGD. Chapter 530(2)(D)(1) specifies that routine surveillance and screening level testing requirements are as follows:
Sereenini level testin Level WET Testing Priority pollutant testing Analytical chemistry
IV 1 per year* 1 per year* 4 per year*
Surveillance level testin Level WET Testing Priority pollutant testing Analytical chemistry
IV 1 per year* None required* 1 per year*ME0101311 FACT SHEET Page 14 of 17

W002672-6B-D-R 6. EFFLUENT LIMITATIONS & MONITORING REQUIREMENTS (cont'd)

Chapter 530(2)(D)(1) states: *These routine testing requirements for Level IV are waived, except that the Department shall require an individual discharger to conduct testing under the following conditions. (a) The discharger's permit application or information available to the Department indicate that toxic compounds may be present in toxic amounts; or (b) Previous testing conducted by the discharger or similar dischargers indicates that toxic compounds may be present in toxic amounts. The previous permit waived all WET, analytical chemistry and priority pollutant testing pursuant to 06-096 CMR Chapter 530, Surface Water Toxics Control Program. Based on the information available to date, the Department has made a best professional judgment determination to once again waive all surveillance and screening level testing for the permittee. Special Condition I, 06-096 CMR 530(D)(2)(4) Statement For Reduced/Waived Toxics Testing, of this permit requires the permittee to submit an annual certification indicating the discharge from the facility has not change changed substantially since the previous permitting action. However, should there be a substantial change in the characteristics of the discharge in the future, the Department may reopen this permit pursuant to Special Condition K, Reopening Of Permit For Modifications, to incorporate the applicable WET, priority pollutant and or analytical testing requirements cited above.
i. Mercury — Pursuant to Certain deposits and discharges prohibited, Maine law, 38 M.R.S.A. § 420 and Waste discharge licenses, 38 M.R.S.A. § 413 and Interim Effluent Limitations and Controls for the Discharge of Mercury, 06-096 CMR 519 (last amended October 6, 2001), the Department established a 2/Year monitoring frequency for total mercury. The Department notified the permittee that interim average and maximum limits for mercury were established as 7.2 ng/L and 10.9 ng/L respectively, which are being carried forward in this permitting action. Maine law 38 M.R.S.A., §420 1-B,(B)(1) states that a facility is not in violation of the AWQC for mercury if the facility is in compliance with an interim discharge limit established by the Department pursuant to section 413, subsection 11. A review of the Department's data base for the period October 1999 through the present indicates the permittee has been in compliance with the interim limits for mercury as results have been reported as follows; Mercury n = 3 Value Limit (ng/L) Range (ng/L) Mean (ng/L) Average 7.2 3.5 — 6.35 4.4 Maximum 10.9 3.5 — 6.3 4.4ME0101311 FACT SHEET Page 15 of 17

W002672-6B-D-R 6. EFFLUENT LIMITATIONS & MONITORING REQUIREMENTS (cont'd) The review of the monitoring data for total and mercury indicates the ratios (expressed in percent) of the long term effluent average to the average limit can be calculated as follows: Mercury Long term average — 4.4 ng/L Average limit = 7.2 ng/L Current monitoring frequency 2/Year Ratio = 4.4 riga, = 61% 7.2 ng/L Pursuant to Maine law 38, M.R.S.A. §420, sub-§1-B, IF, this permitting action is reducing the monitoring frequency from 2/Year to 1/Year. Total Phosphorus and Ortho-phosphorus — The previous permitting action established a seasonal (May — October) 1/Week monitoring and daily maximum concentration reporting requirement for total phosphorus and ortho-phosphorus. A review of the monthly Discharge Monitoring Report (DMR) data for the period May 2011 through July 2012 indicates values have been reported as follows; Total nhosnhorus MRs=8 Value Limit (mg/L) Range (mg/L) Mean (mg/L) Daily Maximum Report 1.5 — 4.9 3.4 Ortho- hos horns (DMRs=8 Value Limit (mg/L) Range (mg/L) Mean (mg/L) Daily Maximum Report 1.4 — 4.9 3.2 A Department report entitled, Penobscot River Phosphorus Waste Load Allocation, May 2011 stating seasonal mass based total phosphorus limitations are necessary for four industrial dischargers on the river as well as monitoring for total phosphorus for five municipal waste water treatment facilities. The PIN facility was not named as a facility required to monitor for phosphorus. Therefore, this permitting action is eliminating the monitoring and reporting requirements for both total phosphorus and ortho-phosphorus.ME0101311 FACT SHEET Page 16 of 17

7. ANTI-DEGREDATION - IMPACT ON RECEIVING WATER QUALITY Maine's anti-degradation policy is included in 38 M.R.S.A., Section 464(4)(F) and addressed in the Conclusions section of this permit. Pursuant to the policy, where a new or increased discharge is proposed, the Department shall determine whether the discharge will result in a significant lowering of existing water quality. Increased discharge means a discharge that would add one or more new pollutants to an existing effluent, increase existing levels of pollutants in an effluent, or cause an effluent to exceed one or more of its current licensed discharge flow or effluent limits, after the application of applicable best practicable treatment technology. This permitting action revises previously established mass limitations for BOD and TSS to correct an error in the calculation of the limits in the previous permit. The rationale for these actions is contained in Section 6(c) of this Fact Sheet. Based on the information provided in the referenced section, the Department has made the determination that the discharge approved by this permit will not result in a significant lowering of water quality. As permitted, the Department has determined the existing and designated water uses will be maintained and protected and the discharge will not cause or contribute to the failure of the Penobscot River to meet standards for Class B classification.
8. PUBLIC COMMENTS Public notice of this application was made in the Bangor Daily newspaper on October 19, 2012. The Department receives public comments on an application until the date a final agency action is taken on that application. Those persons receiving copies of draft permits shall have at least 30 days in which to submit comments on the draft or request a public hearing, pursuant to Chapter 522 of the Department's rules.

A. GENERAL PROVISIONS 1. General compliance. All discharges shall be consistent with the terms and conditions of this permit; any changes in production capacity or process modifications which result in changes in the quantity or the characteristics of the discharge must be authorized by an additional license or by modifications of this permit; it shall be a violation of the terms and conditions of this permit to discharge any pollutant not identified and authorized herein or to discharge in excess of the rates or quantities authorized herein or to violate any other conditions of this permit. 2. Other materials. Other materials ordinarily produced or used in the operation of this facility, which have been specifically identified in the application, may be discharged at the maximum frequency and maximum level identified in the application, provided: (a) They are not (i) Designated as toxic or hazardous under the provisions of Sections 307 and 311, respectively, of the Federal Water Pollution Control Act; Title 38, Section 420, Maine Revised Statutes; or other applicable State Law; or (ii) Known to be hazardous or toxic by the licensee. (b) The discharge of such materials will not violate applicable water quality standards. 3. Duty to comply. The permittee must comply with all conditions of this permit. Any permit noncompliance constitutes a violation of State law and the Clean Water Act and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or denial of a permit renewal application. (a) The permittee shall comply with effluent standards or prohibitions established under section 307(a) of the Clean Water Act, and 38 MRSA, §420 or Chapter 530.5 for toxic pollutants within the time provided in the regulations that establish these standards or prohibitions, even if the permit has not yet been modified to incorporate the requirement. (b) Any person who violates any provision of the laws administered by the Department, including without limitation, a violation of the terms of any order, rule license, permit, approval or decision of the Board or Commissioner is subject to the penalties set forth in 38 MRSA, §349. 4. Duty to provide information. The permittee shall furnish to the Department, within a reasonable time, any information which the Department may request to determine whether cause exists for modifying, revoking and reissuing, or terminating this permit or to determine compliance with this permit. The permittee shall also furnish to the Department upon request, copies of records required to be kept by this permit. 5. Permit actions. This permit may be modified, revoked and reissued, or terminated for cause. The filing of a request by the permittee for a permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any permit condition. 6. Reopener clause. The Department reserves the right to make appropriate revisions to this permit in order to establish any appropriate effluent limitations, schedule of compliance or other provisions which may be authorized under 38 MRSA, §414-A(5).

7. Oil and hazardous substances. Nothing in this permit shall be construed to preclude the institution of any legal action or relieve the permittee from any responsibilities, liabilities or penalties to which the permittee is or may be subject under section 311 of the Federal Clean Water Act; section 106 of the Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980; or 38 MRSA §§ 1301, et. seq.
8. Property rights. This permit does not convey any property rights of any sort, or any exclusive privilege.
9. Confidentiality of records. 38 MRSA §414(6) reads as follows. "Any records, reports or information obtained under this subchapter is available to the public, except that upon a showing satisfactory to the department by any person that any records, reports or information, or particular part or any record, report or information, other than the names and addresses of applicants, license applications, licenses, and effluent data, to which the department has access under this subchapter would, if made public, divulge methods or processes that are entitled to protection as trade secrets, these records, reports or information must be confidential and not available for public inspection or examination. Any records, reports or information may be disclosed to employees or authorized representatives of the State or the United States concerned with carrying out this subchapter or any applicable federal law, and to any party to a hearing held under this section on terms the commissioner may prescribe in order to protect these confidential records, reports and information, as long as this disclosure is material and relevant to any issue under consideration by the department."
10. Duty to reapply. If the permittee wishes to continue an activity regulated by this permit after the expiration date of this permit, the permittee must apply for and obtain a new permit.
11. Other laws. The issuance of this permit does not authorize any injury to persons or property or invasion of other property rights, nor does it relieve the permittee if its obligation to comply with other applicable Federal, State or local laws and regulations.
12. Inspection and entry. The permittee shall allow the Department, or an authorized representative (including an authorized contractor acting as a representative of the EPA Administrator), upon presentation of credentials and other documents as may be required by law, to: (a) Enter upon the permittee's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this permit; (b) Have access to and copy, at reasonable times, any records that must be kept under the conditions of this permit; (c) Inspect at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this permit; and (d) Sample or monitor at reasonable times, for the purposes of assuring permit compliance or as otherwise authorized by the Clean Water Act, any substances or parameters at any location.

B. OPERATION AND MAINTENACE OF FACILITIES 1. General facility requirements. (a) The permittee shall collect all waste flows designated by the Department as requiring treatment and discharge them into an approved waste treatment facility in such a manner as to

Revised July 1, 2002 Page 3MAINE POLLUTANT DISCHARGE ELIMINATION SYSTEM PERMIT STANDARD CONDITIONS APPLICABLE TO ALL PERMITS maximize removal of pollutants unless authorization to the contrary is obtained from the Department. (b) The permittee shall at all times maintain in good working order and operate at maximum efficiency all waste water collection, treatment and/or control facilities. (c) All necessary waste treatment facilities will be installed and operational prior to the discharge of any wastewaters. (d) Final plans and specifications must be submitted to the Department for review prior to the construction or modification of any treatment facilities. (e) The permittee shall install flow measuring facilities of a design approved by the Department. (f) The permittee must provide an outfall of a design approved by the Department which is placed in the receiving waters in such a manner that the maximum mixing and dispersion of the wastewaters will be achieved as rapidly as possible.
2. Proper operation and maintenance. The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the permit.
3. Need to halt or reduce activity not a defense. It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit.
4. Duty to mitigate. The permittee shall take all reasonable steps to minimize or prevent any discharge or sludge use or disposal in violation of this permit which has a reasonable likelihood of adversely affecting human health or the environment.
5. Bypasses. (a) Definitions. (i) Bypass means the intentional diversion of waste streams from any portion of a treatment facility. (ii) Severe property damage means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. (b) Bypass not exceeding limitations. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of paragraphs (c) and (d) of this section. (c) Notice. (i) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass.

Revised July I, 2002 Page 4MAINE POLLUTANT DISCHARGE ELIMINATION SYSTEM PERMIT STANDARD CONDITIONS APPLICABLE TO ALL PERMITS (ii) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in paragraph D(1)(0, below. (24-hour notice). (d) Prohibition of bypass. (i) Bypass is prohibited, and the Department may take enforcement action against a permittee for bypass, unless: (A) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; (B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (C) The permittee submitted notices as required under paragraph (c) of this section. (ii) The Department may approve an anticipated bypass, after considering its adverse effects, if the Department determines that it will meet the three conditions listed above in paragraph (d)(i) of this section. 6. Upsets. (a) Definition. Upset means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. (b) Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of paragraph (e) of this section are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. (c) Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (i) An upset occurred and that the permittee can identify the cause(s) of the upset; (ii) The permitted facility was at the time being properly operated; and (iii) The permittee submitted notice of the upset as required in paragraph D(1)(f) , below. (24 hour notice). (iv) The permittee complied with any remedial measures required under paragraph B(4). (d) Burden of proof. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has the burden of proof.

Interference means a Discharge which, alone or in conjunction with a discharge or discharges from other sources, both: (1) Inhibits or disrupts the POTW, its treatment processes or operations, or its sludge processes, use or disposal; and (2) Therefore is a cause of a violation of any requirement of the POTW's NPDES permit (including an increase in the magnitude or duration of a violation) or of the prevention of sewage sludge use or disposal in compliance with the following statutory provisions and regulations or permits issued thereunder (or more stringent State or local regulations): Section 405 of the Clean Water Act, the Solid Waste Disposal Act (SWDA) (including title II, more commonly referred to as the Resource Conservation and Recovery Act (RCRA), and including State regulations contained in any State sludge management plan prepared pursuant to subtitle D of the SWDA), the Clean Air Act, the Toxic Substances Control Act, and the Marine Protection, Research and Sanctuaries Act. Maximum daily discharge limitation means the highest allowable daily discharge. New source means any building, structure, facility, or installation from which there is or may be a discharge of pollutants, the construction of which commenced:

(a) After promulgation of standards of performance under section 306 of CWA which are applicable to such source, or (b) After proposal of standards of performance in accordance with section 306 of CWA which are applicable to such source, but only if the standards are promulgated in accordance with section 306 within 120 days of their proposal. Pass through means a discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of a violation of any requirement of the POTW's NPDES permit (including an increase in the magnitude or duration of a violation). Permit means an authorization, license, or equivalent control document issued by EPA or an approved State to implement the requirements of 40 CFR parts 122, 123 and 124.

LEGAL REFERENCES The laws concerning the DEP's Organization and Powers, 38 M.R.S.A. §§ 341-D(4) & 346, the Maine Administrative Procedure Act, 5 M.R.S.A. § 11001, and the DEP's Rules Concerning the Processing of Applications and Other Administrative Matters ("Chapter 2"), 06-096 CMR 2 (April 1, 2003).

How LONG YOU HAVE TO SUBMIT AN APPEAL TO THE BOARD The Board must receive a written appeal within 30 days of the date on which the Commissioner's decision was filed with the Board. Appeals filed after 30 calendar days of the date on which the Commissioner's decision was filed with the Board will be rejected.
How TO SUBMIT AN APPEAL TO THE BOARD Signed original appeal documents must be sent to: Chair, Board of Environmental Protection, c/o Department of Environmental Protection, 17 State House Station, Augusta, ME 04333-0017; faxes are acceptable for purposes of meeting the deadline when followed by the Board's receipt of mailed original documents within five (5) working days. Receipt on a particular day must be by 5:00 PM at DEP's offices in Augusta; materials received after 5:00 PM are not considered received until the following day. The person appealing a licensing decision must also send the DEP's Commissioner a copy of the appeal documents and if the person appealing is not the applicant in the license proceeding at issue the applicant must also be sent a copy of the appeal documents. All of the information listed in the next section must he submitted at the time the appeal is filed. Only the extraordinary circumstances described at the end of that section will justify evidence not in the DEP's record at the time of decision being added to the record for consideration by the Board as part of an appeal.
WHAT YOUR APPEAL PAPERWORK MUST CONTAIN Appeal materials must contain the following information at the time submitted: OCF/90-1/r95/r981r9M00/r04/02Appealing a Commissioner's Licensing Decision March 2012 Page 2 of 3 1. Aggrieved Status. The appeal must explain how the person filing the appeal has standing to maintain an appeal. This requires an explanation of how the person filing the appeal may suffer a particularized injury as a result of the Commissioner's decision. 2. The findings, conclusions or conditions objected to or believed to be in error. Specific references and facts regarding the appellant's issues with the decision must be provided in the notice of appeal. 3. The basis of the objections or challenge. If possible, specific regulations, statutes or other facts should be referenced. This may include citing omissions of relevant requirements, and errors believed to have been made in interpretations, conclusions, and relevant requirements. 4. The remedy sought. This can range from reversal of the Commissioner's decision on the license or permit to changes in specific permit conditions. 5. All the matters to be contested. The Board will limit its consideration to those arguments specifically raised in the written notice of appeal. 6. Request for hearing. The Board will hear presentations on appeals at its regularly scheduled meetings, unless a public hearing on the appeal is requested and granted. A request for public hearing on an appeal must be filed as part of the notice of appeal. 7. New or additional evidence to be offered. The Board may allow new or additional evidence, referred to as supplemental evidence, to be considered by the Board in an appeal only when the evidence is relevant and material and that the person seeking to add information to the record can show due diligence in bringing the evidence to the DEP's attention at the earliest possible time in the licensing process or that the evidence itself is newly discovered and could not have been presented earlier in the process. Specific requirements for additional evidence are found in Chapter 2.
OTHER CONSIDERATIONS IN APPEALING A DECISION TO THE BOARD 1, Be familiar with all relevant material in the DEP record. A license application file is public information, subject to any applicable statutory exceptions, made easily accessible by DEP. Upon request, the DEP will make the material available during normal working hours, provide space to review the file, and provide opportunity for photocopying materials. There is a charge for copies or copying services. 2. Be familiar with the regulations and laws under which the application was processed, and the procedural rules governing your appeal. DEP staff will provide this information on request and answer questions regarding applicable requirements. 3. The filing of an appeal does not operate as a stay to any decision. If a license has been granted and it has been appealed the license normally remains in effect pending the processing of the appeal. A license holder may proceed with a project pending the outcome of an appeal but the license holder runs the risk of the decision being reversed or modified as a result of the appeal.
WHAT TO EXPECT ONCE YOU FILE A TIMELY APPEAL WITH THE BOARD The Board will formally acknowledge receipt of an appeal, including the name of the DEP project manager assigned to the specific appeal. The notice of appeal, any materials accepted by the Board Chair as supplementary evidence, and any materials submitted in response to the appeal will be sent to Board members with a recommendation from DEP staff. Persons filing appeals and interested persons are notified in advance of the date set for Board consideration of an appeal or request for public hearing. With or without holding a public hearing, the Board may affirm, amend, or reverse a Commissioner decision or remand the matter to the Commissioner for further proceedings. The Board will notify the appellant, a license holder, and interested persons of its decision.

OCF/90-1 /r/9511.98/r99/r001r041112Appealing a Commissioner's Licensing Decision March 2012 Page 3 of 3 IL JUDICIAL APPEALS Maine law generally allows aggrieved persons to appeal final Commissioner or Board licensing decisions to Maine's Superior Court, see 38 M.R.S.A. § 346(1); 06-096 CMR 2; 5 M.R.S.A. § 11001; & M.R. Civ, P 80C. A party's appeal must be filed with the Superior Court within 30 days of receipt of notice of the Board's or the Commissioner's decision. For any other person, an appeal must be filed within 40 days of the date the decision was rendered. Failure to file a timely appeal will result in the Board's or the Commissioner's decision becoming final. An appeal to court of a license decision regarding an expedited wind energy development, a general permit for an offshore wind energy demonstration project, or a general permit for a tidal energy demonstration project may only be taken directly to the Maine Supreme Judicial Court. See 38 M.R.S.A. § 346(4). Maine's Administrative Procedure Act, DEP statutes governing a particular matter, and the Maine Rules of Civil Procedure must be consulted for the substantive and procedural details applicable to judicial appeals.

ADDITIONAL INFORMATION If you have questions or need additional information on the appeal process, for administrative appeals contact the Board's Executive Analyst at (207) 287-2452 or for judicial appeals contact the court clerk's office in which your appeal will be filed.
