US EPA Representative(s): Stephanie Tougas Eleanor Horvath ED_019088A_00020390-00001 D. State / Local Representative(s): None E. Federally Enforceable Requirements Covered During the Inspection: EPA 2022 Construction General Permit F. Previous Enforcement Actions: None III. Type and Purpose of Inspection Compliance Evaluation IV. Facility Description The site (Highland Vale) is an approximately 20-acre site located off Hill Road in Woburn, MA. The site we focused our inspection on is part of a larger master development plan to redevelop the former site of Kraft Atlantic Gelatin Company. Prior to building homes, the site had undergone remediation work associated with environmental impacts of the gelatin company. The site directly abuts the Aberjona River wetland complex. V. Inspection I tried calling the facility the morning of the inspection, but I could not reach anyone with the phone number listed on the NOI. We arrived at approximately 11:00 AM. A. Opening Conference Upon arrival, we asked site workers where we could find the site manager / foreman. We were directed to Mr. Patrick Erban, who introduced himself as the construction manager. I presented my credentials, provided a copy of the Small Business Resources Information Sheet, and explained the purpose of the inspection. He then brought us to the construction trailer on site, where he introduced us to Mr. Rich Fruci, Director of Construction for the Pulte Group. I asked if they had a SWPPP on site, to which they showed me a copy of the SWPPP and showed me the template for the inspection reports Mr. Erban completes. I asked how often he inspects, to which he responded every week and after a large storm event. I flipped through the SWPPP and said I may follow up to request a digital copy for further review. 2 ED_019088A_00020390-00002 B. Facility Tour EPA and Mr. Erban began a site tour, walking along the southern perimeter downslope towards the western edge of the property. As we walked, I observed silt fences and silt socks, as well as a concrete wash out area. I asked how they communicated stormwater control issues, to which Mr. Erban said that he summarizes findings to a contractor, JT Lynch, and they come on site and fix the stormwater erosion controls. Mr. Erban also explained that a third party, Marchionda and Associates, developed the stormwater control plans and did a lot of the engineering. He also explained that because of a Woburn special permit requirement, Marchionda comes on site to conduct similar stormwater control inspections as he does. We continued walking downslope towards the west end of the site. We observed detention basins, to which Mr. Erban explained that these basins were temporary and permanent ones will eventually be installed. He also explained that they are currently installing the catch basin system onsite to collect stormwater and keep it onsite. At the bottom of the slope below the basins we observed multiple rows of silt fences abutting the wetland complex. We then walked down the grassy throughway that Mr. Erban explained was an MWRA easement towards the Aberjona River's edge. We got to the edge of the river (which is approximately 275 feet from the bottom of the slope / edge of the property) and observed silt fences that were in the water. This area, Mr. Erban explained, was not the site's property. I mentioned that we should try to find out who is responsible for maintaining these erosion controls at the river's edge. We then walked back up towards the site to the tow of the slope, where we observed water flowing out of the slope, breaching erosion controls and into the wetland complex. The flow was substantial, which Mr. Erban attributed to both the storm event the day prior as well as due to the heavy blasting that had occurred in the area, and so he believes it could be groundwater. Mr. Erban believes when the catch basins are installed this flow will be more controlled. We continued north along the west edge of the site and veering back east towards the trailer where we concluded the site walk. C. Closing Conference I said that they should address the silt fences that need fixing and that I may be following up to request copies of inspection reports and SWPPP. I said I would follow up with a copy of the inspection report within 60 days. We departed at approximately 11:45 AM. After the inspection, Mr. Erban emailed me copies of the SWPPP as well as copies of his inspection reports on 12/20/2023. 3 ED_019088A_00020390-00003 Unless otherwise noted, this report describes conditions at the facility / property as observed by EPA inspector(s), and / or through records provided to and / or information reported to EPA inspector(s) by facility representatives and as understood by the inspector(s).
