Welcome and Sign In Former Market Street Gas Works Site Remediation and Restoration Project – Area D What is a Manufactured Gas Plant? Before common availability of natural gas, “manufactured” gas was created by heating coal in a specialized oven. Pictured here is an MGP located in Morristown, NJ at the turn of the 20th Century. Site History • A predecessor of Public Service Electric and Gas Company (PSE&G) operated an MGP in Newark until the early 1900s along Market Street/Raymond Boulevard. • Manufactured gas was used for street lighting, heating and cooking. • Many useful chemical byproducts were produced, such as coke, ammonia, creosote, oils, benzene and tar. Manufactured Gas Plant Environmental Impacts • Byproducts resulted in soil and groundwater contamination. • PSE&G has 38 former Manufactured Gas Plant sites in New Jersey that are required to be cleaned up, including the Market Street Gas Works site. Remediation Status Area A – Remediation Completed Area C – Remediation Completed Area B – Remediation Completed Area D – Remediation Began August 2014 Project Overview – Area D • Area D is located at the corner of Market and Prospect streets (418-428 Market Street). • Work began in August and expected completion is early 2015. • The purpose of the work is to remediate approximately 65,000 tons of soil impacted by the former plant’s historic operations. Approximately 31,000 tons of impacted soil will be removed and replaced with clean fill. Approximately 34,000 tons of soil, at depths greater than 14 feet below ground surface, will be treated with cement and contained onsite. • This work is being conducted in accordance with the regulations of the New Jersey Department of Environmental Protection and under the oversight and direction of the site’s Licensed Site Remediation Professional. Area D – Current Condition What You Can Expect to See Personnel and equipment moving to the site The first few weeks of work in August 2014 focused on preparing the property to be remediated, moving construction equipment into place and establishing temporary office space. What You Can Expect to See Work to Stabilize Work Area – Using Steel Sheeting and Underground Concrete Columns The excavation area will be stabilized by installing a sheet pile wall around three sides of the work area perimeter. The work area closest to the adjacent building on Prospect Street will be supported by the creation of subsurface concrete columns, to minimize noise and vibrations closest to the structure. Location of sheeting line Location of planned underground concrete columns Example of sheeting What You Can Expect to See Manage Surface/Groundwater Removal of the affected soil Surface water from rain events will be controlled along with some dewatering of groundwater. Water will be stored and shipped offsite for treatment and disposal. Soil will be excavated and stabilized, then trucked offsite for treatment, recycling and/or disposal at a certified facility. Protecting Public Health & Safety Safety Protection Measures PSE&G is committed to meeting the project’s goals in a manner that puts the health and safety of the public and the project’s workers first • Site fencing The work site will be secured and only authorized personnel will be allowed to enter. • Underground utility mark out In addition to calling NJ One Call, PSE&G performs its own mark outs to ensure nothing is overlooked or mismarked. • Truck trailers will be covered Trucks will be washed, lined and covered prior to exiting the site. Protecting Public Health & Safety Health Protection Measures PSE&G is committed to meeting the project’s goals in a manner that puts the health and safety of the public and project’s workers first Protect workers Safety and protection gear includes special clothing, gloves and boots as required by the federal Occupational Safety and Health Administration. Minimize dust and odors Work will be conducted as an open-air excavation, similar to excavation activities performed previously at the site. Standard dust and vapor control measures such as water mist, foam spray, and plastic sheeting will be used as needed to control potential dust and odors. Air monitors will be installed along the perimeter of the work area to ensure air quality is maintained. Protecting Public & Private Property Additional Monitoring Measures Noise monitoring Decibel levels will be monitored. Vibration monitoring Offsite vibrations will be monitored using portable seismographs placed at offsite properties. Noise monitoring using hand-held decibel reader Portable seismograph for vibration monitoring Surveying tripod Survey reference point Settlement monitoring Pre- and post-construction structural evaluations of nearby structures will be conducted to ensure that our activities do not result in impacts to properties due to settlement issues. Minimizing Offsite Impacts Truck Route and Use of Traffic Control • • • A truck route will be planned in cooperation with the City. To protect pedestrians and local traffic, a flagger and an off duty police officer will be used when required. No trucks will travel on Ferry Street. Proposed route for trucks entering site Proposed route for trucks exiting site PSE&G Project Team • PSE&G Project Manager – Jacques Benaroch, P.E. • The environmental consulting firm ERM will provide engineering oversight of the day-to-day operations of the project on behalf of PSE&G. • Creamer Environmental, Inc. will be the construction company performing the work. Our Commitment to the Community PSE&G is committed to keeping the MGP site’s neighbors and the City of Newark informed of our plans and activities If you have a question or concern, please contact us directly and we’ll do our best to provide you with the information you need. Planned Community Outreach Efforts • Regular updates to City Officials • Regular project updates to site neighbors For More Information Visit our website: newarkmgp.com Or Call our Community Information Line at: (866) 520-6765 PSE&G Community Liaison, Tony Bianchini, will respond to your call.
