Type and Purpose of Inspection(s) The purpose of the reconnaissance inspection was to evaluate access requirements of various locations along Bloody Brook, while noting appearance and presence of flow for one or more sampling inspections. The purpose of the sampling inspection was to identify potential illicit connections or illegal discharges within the City of Methuen, MA MS4 that may adversely impact the water quality in Bloody Brook. Samples were collected from eight (8) locations in accordance with the FSB Investigations Team Stormwater Program Plan. Sample sites were identified during a reconnaissance inspection conducted on 08/24/2022. V. Permittee Details The City of Methuen, MA occupies approximately 23 square miles in Essex County, MA, approximately 30 miles northwest of Boston, MA. The City of Methuen shares borders with the municipalities of Haverhill to the northeast, North Andover to the east, Lawrence and Andover to the south, Dracut (Middlesex County) to the west, Pelham, New Hampshire (Hillsborough County) to the northwest, and Salem, New Hampshire (Rockingham County) to the north. According to the 2020 U.S. Census, the regulated population of Methuen was 53,059. Bloody Brook is listed as an MS4 receiving water in the City of Methuen Notice of Intent (NOI) for coverage under the permit. VI. 08/24/2022 Reconnaissance Inspection Summary On Wednesday, August 24, 2022, EPA employees Shannon Brunelle and Michelle Coombs (" the EPA Inspection Team ") conducted an unannounced reconnaissance inspection of the City of Methuen MS4. They were not accompanied by any city or state representatives. The inspection started at approximately 11:15 AM where Bloody Brook flows underground at the CVS on Jackson St. At the time of the inspection, the weather was approximately 70 F with mostly cloudy skies. According to the National Weather Service (NWS) for the Lawrence Municipal Airport (KLWM), the last precipitation event prior to the inspection occurred on August 23, 2022, with 0.05 inches recorded. There was 0.27 inches precipitation recorded within the 72 hours before the inspection. In the month of August (to date), the area observed 0.52 inches of rain, which is Page 2 of 19 Sampling Inspection Date: 09/06/2022 ED_019088A_00004718-00002 City of Methuen, MA (MA041210) EPA MS4 Compliance Sampling Inspection approximately 22% of the 30-year normal value of 2.38 inches. According to the US Drought Monitor, as of 08/30/2022, Essex County was experiencing extreme drought conditions. None of the locations visited during this inspection were field screened with the test kits or the YSI quality meter. Locations visited were noted for appearance, presence of flow, and access requirements. Photographs taken during the inspection are listed in Appendix A. VII. 09/06/2022 Sampling Inspection Summary On Tuesday, September 6, 2022, EPA employees Michelle Coombs and Caitlin Brown (" the EPA Inspection Team ") conducted an unannounced compliance sampling inspection of the City of Methuen, MA MS4 at the locations described in Section VIII. They were not accompanied by any city or state representatives. The inspection started at approximately 10 AM where Bloody Brook flows underground at the CVS on Jackson St. At the time of the inspection, the weather was approximately 70 F and raining with overcast skies. According to the NWS for the KLWM, the last precipitation event prior to the inspection occurred on September 5, 2022, with 1.25 inches recorded. In the month of September (to date), 1.85 inches of rain was observed, which is approximately 264% normal of the 30-year normal value of 0.70 inches. According to the US Drought Monitor, as of September 6, 2022, Essex County is experiencing severe to extreme drought conditions. The sampling locations described in Section VIII were not field screened with the test kits for ammonia (nitrogen), surfactants, and total chlorine due to high flow conditions and a strong dilution factor potential, with the exception of " BrookOut ". In - situ measurements were taken using a YSI meter for specific conductivity, salinity, and temperature at all locations. All field data were recorded on field data sheets. Samples were delivered to and analyzed for E. coli and Enterococcus and PPCPs at the EPA New England Regional Laboratory (NERL) in North Chelmsford, MA. Table 1 below summarizes the sampling and analytical data. VIII. Description of Sampling Locations (in order of collection time) Photographs depicting each sample location are included in Appendix A of this report. * CVS: An in - stream sample of Bloody Brook collected near the CVS parking lot at the corner of Jackson Street and Swan Street. Some trash and duckweed was observed floating on the stream surface. Sample was collected from the stream prior to the reinforced concrete inflow pipe that flows under the parking lot. The outfall adjacent to this inflow point was dry and not flowing. * Curtis: An in - stream sample of Bloody Brook collected at a single steel ovular stream culvert approximately 30 inches in diameter located on Curtis Street near the intersection with Bicknell Avenue. Discharge flow was approximately 50 gallons per minute (gpm) and is Bloody Brook upstream of " CVS ". Sample was collected at the mouth of the culvert. A smaller concrete outfall to the left of the culvert was flowing, and upon further examination, the flow was coming from a catch basin nearby on Curtis Street. 47Bick: An in - stream sample of Bloody Brook collected at a single reinforced concrete stream culvert approximately 24 inches in diameter located at 47 Bicknell Street where Bloody Brook daylights from underneath Bicknell Avenue. Stream flow was Page 3 of 19 Sampling Inspection Date: 09/06/2022 ED_019088A_00004718-00003 City of Methuen, MA (MA041210) EPA MS4 Compliance Sampling Inspection approximately 15 gpm and is an upstream location of " Curtis ". Sample was collected at the mouth of the culvert. 96East: An in - stream sample of Bloody Brook collected at a concrete stream culvert where the brook flows underneath East Street near the intersection with Jackson Street. Outfall characteristics could not be determined due to thick vegetation overgrowth over the culvert. Sample was collected at the base of the vegetation, approximately 6 inches from the mouth of the culvert. BrookOut: A single concrete outfall approximately 15 inches in diameter located adjacent to 180 Jackson Street. Discharge flow was approximately 5-7 gpm into Bloody Brook. Sample was collected at the mouth of the outfall. Brook: An in - stream sample of Bloody Brook collected at a rectangular stream culvert that directs flow underneath Brook Street near the intersection of Jackson Street. Sample was collected at the mouth of the culvert. Trash was observed downstream along both banks. * Cedar: A single white PVC pipe approximately 24 inches in diameter located on the south side of the Cedar View Nursing Home. Discharge flow was approximately 12-15 gpm. A slight musty odor was detected. Sample was collected at the mouth of the outfall. * Dearborn: An in - stream sample of Bloody Brook collected at a singular steel stream culvert approximately 48 inches in diameter where the brook flows underneath Dearborn Road. Discharge flow was approximately 50 gpm. Some trash was observed downstream and along the banks. Orange staining of the sediment was observed, and a slight musty odor was detected. Sample was collected at the mouth of the culvert.

With respect to all of the above compounds, when a sanitary sewage source is present, depending on the type of source, distance from the sample location, and the strength of the source, concentrations of these compounds may range from the low ng / l range up to thousands of ng / L.
