U.S. Environmental Protection Agency Background Summary Memorandum - Roundhouse Parking Lot, Northampton, Massachusetts 1.0 INTRODUCTION This Background Summary Memorandum for the property known as the Roundhouse Parking Lot has been prepared in accordance with the Work Plan developed by Metcalf & Eddy (1999) for conducting the Targeted Brownfields Assessments (TBAs) Work Assignment Number 043-SIBZ-O1ZZ, under EPA's Response Action Contract (RAC). The Roundhouse municipal parking lot area is located off of Old South Street in Northampton, Massachusetts. The purpose of this memorandum is to summarize reasonably available information related to the site for use by M&E and its client, the EPA, for developing the scope of work for conducting subsequent assessment activities in support of the objectives of the EPA's TBA program. In preparation of this memorandum, M&E conducted the following activities: A review of historical maps and photographs obtained from the Department of Planning and Development, and review of historical Sanborn Fire Insurance Maps obtained by Environmental Data Resources (EDR). I - A review of the Cultural Resource Survey Report and a deeds search prepared for the site. - A review of the searchable site database from the Massachusetts Department of Environmental Protection (MADEP)for release sites near the property. - A limited site inspection of the subject property for observation of present conditions and general features. Discussions with local and state points-of-contact (POCs) for the site, including the Planning and Development Department, the Northampton Fire Department, and the Engineering Department. No sampling activities were conducted as part of the development of this memorandum. Site * background and overview are presented in the following sections. I U.S. Environmental Protection Agency K IMwBackground Summary Memorandum - Roundhouse Parking Lot, Northampton, Massachusetts 2.0 SITE INFORMATION OVERVIEW 2.1 Location The site is described as the Roundhouse Parking Lot by the Planning and Development Department of the City of Northampton. The site location is shown in Figure 1. The site consists mostly of a paved parking lot for a bus terminal and for public parking. It is bordered by the bus terminal (Roundhouse Plaza) building and Old South Street to the east, and a residential apartment building and New South Street (Route 10) to the west. The northern limits of the site are bounded by municipal offices (the 3 story brick office building), the Unitarian Church, Memorial Hall, and Pulaski Park (Figure 2). Structures within the site include the converted gas holder (roundhouse) and associated red brick building (Purifier house), which are now privately owned and used for commercial businesses. The lots currently owned by the City, which are the focus of this TBA, encompass the entire parking lot and consist of lots 167 and 246, which are identified on the Northampton Assessors and Zoning Map, Sheet 31D. The renovated roundhouse and associated building are located on lot 251, which is privately owned. 2.2 Site History Information relative to site ownership and historical use was obtained from historical plans and figures, a deeds search performed by Tech Law, and the Cultural Resource Survey Report Crafts Avenue - Gas Company "Roundhouse" Project Area (Drinkwater, 1976). Most of the site was developed by 1855 with the construction of the New Haven and Northampton Railroad and the Northampton Gas Light Company Gas Works (gas works) (Appendix A). A sewer system was installed within the site in 1889 (location unknown). By 1911, the gas works consisted of coal storage buildings, a tar well/storage structure, two gas holders (also called relief holders), a purifying house, and a water gas house and other features (Figure 2). As presented in historical maps and figures, including historical Sanborn Insurance maps, the gas works system of structures can be summarized as follows: 2 M 94 U.S. Environmental Protection Agency Background Summary Memorandum - Roundhouse Parking Lot, Northampton, Massachusetts The existing brick roundhouse office building and attached rectangular office building were once known as the relief holder #1 and the purifying house, respectively. The relief holder, also known as a gasometer, gas holder, or roundhouse, was constructed to encompass an iron gas holder used for the storage of manufactured gas. The purifier house was used to demulsify coal tar and remove sulfur and cyanide from the gas. Immediately west of the purifying house was another relief holder constructed some time around 1895. Coal sheds bordered relief holder #2 to its west and south. An additional purifier was constructed to its west by 1930. Also, a structure labeled gas oil tank appeared in the southwest corner by this period. Brick structures that housed the condenser and engine rooms bordered the roundhouse to its south. Further south was the retort building, where coal carbonization, or coal gasification, took place. Just southeast of the roundhouse (about 50 feet), another cylindrical structure existed that was used initially as a relief holder, and then for storage, including the storage of coal tar. It contained a tar well that was likely below grade. Smaller structures around the tar well included a chimney, a water gas tar well, and a water gas tar separator. Both the well and separator were built below grade, at least partially. To the east of the roundhouse and north of the tar well was the water gas plant. Further east, abutting the tar well and gas plant, was a coke storage shed and area. An oil tank of unknown size was located just north of the coke storage area. The gas works office building was located near the northwest corner of the site. South of the gas works facility was the New Haven and Northampton railroad tracks. The Mill River was also located south of the plant, just south of the tracks (re-routed in the early 1940s). An extensive pipe work layout is shown on a 1911 blue print that connects to most of the buildings. Pipes are also shown leading from the engine room towards the railroad tracks, and possibly the former Mill River. Their former purpose is not known, but may have been used to discharge wastewater and/or to supply water to the facility. 3 U.S. Environmental Protection Agency Massachusetts WI Background Summary Memorandum - Roundhouse Parking Lot, Northampton, One historical photograph indicates a tank structure just south of the railroad tracks. Its purpose is not known. Prior to 1941, the Mill River crossed the site along the southern boundary, just south of the former railroad bed. A retaining wall once existed at the edge of the river's bank and may still be partially visible. The river was diverted in the early 1940s and now flows about 2,000 feet to the west of the site. Land south of the Mill River was apparently part of the gas works in 1900 when it was purchased for the construction of an additional gas holder. Coal storage and oil storage facilities were once located south of the railroad tracks. The railroad tracks were abandoned sometime after 1948. Coal gas production was discontinued in 1951. Most of the gas works structures were demolished in 1962 (Drinkwater, 1976), with the exception of the roundhouse and the purifying house. The property was given to the City in 1977 and the portion containing the roundhouse and purifying house was sold to a private developer. Renovations to the buildings were completed in 1986. The remainder of the site is City owned and is used for public parking. The former location of the gas works office building, located in the northwest corner of the site, is now a 3-story brick structure used for municipal offices. 2.3 Current Site Features and Utilities The site is level and is mostly paved. The northern bordering lots are elevated above the site by as much as 20 feet and a retaining wall separates the northern lots from much of the site. A brick municipal office building is located in the northwestern corner of the site. The buildings on the Assessor's lot 251 include the renovated brick roundhouse and purifier house. They are currently used for commercial office space. The buildings are included on the National Register and are included within Northampton's Downtown Historic District (Drinkwater, 1976). Storm drains and sewer pipes cross the site at different locations. A utility plan was not available during this background review; however, M&E will attempt to obtain plans that identify underground utilities for purposes of planning a field investigation. 4 U.S. Environmental Protection Agency SB'S Background Summary Memorandum - Roundhouse Parking Lot, Northampton, Massachusetts 2.4 Summary of Environmental Information for the Site No former environmental assessments or investigations were identified by M&E for this site during the background review of information.
