DASNY – City College of New York Dormitory Construction Project

Manhattan, NY

DASNY_[Converted]

The Dormitory Authority – State of New York (DASNY) retained D&B to conduct an air monitoring program for approximately 9  months during the excavation phase of a large project to construct new dormitory facilities at the City College of New York in  Manhattan. The air monitoring program involved the installation of four perimeter air monitoring stations at upwind, downwind and crosswind locations to monitor volatile organic compounds and particulate emissions emanating from the construction site during the excavation activities. Project specific thresholds were monitored and the client was notified of any exceedances. Monitoring frequency was based upon the activities completed and varied throughout the program, but was generally conducted once per week after an initial phase designed to determine background levels. Monthly reports, summarizing and documenting the gathered data were prepared and submitted to DASNY throughout the project.

Staten Island, NY

DASNY_[Converted]

DASNY also retained the firm to provide engineering/technical oversight related to the construction of a new Staten Island Courthouse building located in St. George on Staten Island. During the excavation phase of this project D&B implemented a  similar air monitoring project to monitor particulate emissions emanating from the construction site. D&B established four air monitoring stations around the perimeter of the site. Daily monitoring was conducted during the initial phase of the excavation activities and the frequency was gradually decreased to once per week in the latter part of the project. If monitoring levels exceeded project-specific parameters, D&B notified the project manager and site supervisor so that corrective action could be implemented. Daily field activity reports were generated to summarize and present data gathered from the air monitoring activities. The results will also be documented in a final project summary report.

NYCSCA – PCB Remediation Project Air Monitoring Program

At the request of the New York City School Construction Authority (NYCSCA), D&B prepared Community Air Monitoring Plans  (CAMPs) in accordance with New York State Department of Environmental Conservation Division of Environmental Remediation Draft DER-10 Technical Guidance for Site Investigation and Remediation (August 2002). The CAMPs were implemented during excavation and backfill activities, which were conducted as part of PCB remediation projects for three schools: Public School (PS) 86Q located in Jamaica, NY; Intermediate School (IS) 131X located in Bronx, NY and PS53R located in Staten Island, NY. The PCB remediation excavation and backfilling activities were ongoing from August 2008 through September 2008.COMMUNITY AIR MONITORING PROGRAM SERVICES

In June 2007, the New York State Education Department published protocols for addressing PCBs in caulking material in school buildings that were constructed or renovated between 1950 and 1977 and undergoing renovation or demolition. The protocol was developed in consultation with the New York State Department of Health to address concerns about properly managing caulk containing PCBs that would be disturbed during building renovation and maintenance. The guidelines included developing a soil sampling plan for the sampling and testing of soil potentially impacted by demolition and renovation projects involving caulks. Window caulk surveys and soil investigations were conducted at PS86Q, IS 131X and PS53R, and it was determined that PCBs were present in the soils located adjacent to the buildings at concentrations greater than 1 part per million (ppm). The NYCSCA then required excavation and backfilling of predetermined areas where PCBs were detected at concentrations greater than 1 ppm. Since high levels of particulates could pose a potential health threat to both the members of the surrounding community as well as the workers on the site, CAMPs were implemented at all three sites.

CAMP activities included continuous monitoring for dust particulates during all intrusive excavation activities. Four CAMP stations, each consisting of a DusTRAK™ aerosol monitor set on a tripod with visible strobe/alarm to alert D&B personnel of any alarm conditions, were installed surrounding the area of ground intrusive activities to accurately capture both upwind and downwind conditions and concentrations were measured continuously throughout the day. Particulate monitoring at each station was conducted with a portable real-time particulate monitor capable of measuring particulate matter less than 10 micrometers in size, and capable of calculating 15-minute running average concentrations. As specified in the CAMP, the action level for the continuous particulate monitoring is if the 15-minute average downwind concentration exceeds 150 micrograms per cubic meter (ug/m3) above the upwind concentration. Whenever the visible alarm was observed the site supervisor was alerted and control measures were implemented to alleviate the alarm condition.

NYCDEP – Rodman’s NYCPD Firing Range Soil Remediation
Bronx, New York

The New York City Department of Environmental Protection (NYCDEP) retained D&B to provide technical support to prepare and implement a 5-year Operation and Maintenance Program at the Rodman’s Neck New York City Police Department Outdoor Firing Range. Part of this project, which included lead remediation in soil from six firing ranges, required air monitoring to ensure that there was no exposure to air-borne lead beyond the immediate work area. The soil was first excavated to a predetermined depth and screened for reclamation and separation of bullet fragments. Three high volume air sampling stations, each consisting of a MIE DR-4000 dust monitor, were strategically placed at the perimeter of each range during the soil excavation and stabilization process Personnel involved in these activities wore low volume personal air sampling pumps to document worker non-exposure to respirable dust particles that potentially contained lead. In addition, real-time monitoring for dust and fugitive emissions was conducted with a MIE PDR-1000 dust monitor with data logging enabled. Filters from both high volume and low volume pumps were sent to a laboratory at the end of each day and analyzed for lead.

The Mount Sinai Medical Center (MSMC) Center of Science and Medicine site is located on an approximately 70,000 square foot parcel at Madison Avenue and East 102nd Street in Manhattan, New York. In order to make way for the construction of the new building, four existing buildings were demolished. The site was excavated to a depth of approximately 50 feet below grade to allow for the construction of the new Center for Science and Medicine.

The firm was responsible for conducting air monitoring during both the demolition and excavation phases to ensure field personnel and the community surrounding the construction site that ambient air quality was not adversely impacted from the on-site activities associated with the project. Air monitoring was conducted utilizing equipment designed to monitor concentrations of volatile organic compounds (VOCs) and particulate matter (PM) in ambient air.COMMUNITY AIR MONITORING PROGRAM SERVICES

VOC monitoring at each station was accomplished utilizing a MiniRAE 2000 photo-ionization detector (PID) equipped with a 10.6 eV lamp capable of calculating 15-minute running average concentrations. PM monitoring at each station was conducted with a Thermo MIE DR-4000 portable real-time particulate monitor capable of measuring particulate matter less than 10 micrometers in size, and capable of calculating 15-minute running average concentrations. Perimeter air monitoring was conducted during the demolition and excavation phases of the project, while work-zone air monitoring was conducted during all excavation operations involving soil on site. Based on the monitoring results, D&B advised the MSMC project manager and the construction management site supervisor if corrective action was necessary to comply with the air monitoring program requirements in the New York City Department of Environmental Protection Remedial Action Plan. The results of the air  monitoring program were recorded and documented in reports prepared for MSMC.

National Grid – Bay Shore MGP Site Air Monitoring
Bay Shore, NY

How to Avoid Tree & Utility Line Conflicts When Selecting and Pl

National Grid retained D&B to conduct daily air monitoring for National Grid throughout the ground intrusive phases of a  project to construct an ozone injection building at the site of a former manufactured gas plant (MGP) located in Bay Shore,
New York. The construction project ran from February through September of 2009. A Phase II investigation of the site had  revealed the potential that petroleum impacted soil would be encountered during excavation. As a result high levels of  particulates could pose a potential health threat to both the members of the surrounding community, as well as the workers on the site. Each day two temporary air monitoring stations were installed in the area of ground intrusive activities to accurately capture both upwind and downwind conditions.COMMUNITY AIR MONITORING PROGRAM SERVICES

Each air monitoring station included a Thermo MIE DR-4000 aerosol monitor for the measurement of particulate matter, a MiniRAE 3000 photo-ionization detector for the measurement of volatile organic compounds, and a tripod with visible strobe/alarm to alert D&B personnel of any alarm conditions. This equipment logged readings once every minute, and this data was downloaded daily to a field laptop. A weather station constructed on site was also used to monitor and record wind conditions throughout the day. Six instantaneous air monitoring stations were located roughly equidistant around the perimeter of the work site. Readings were obtained at these stations once an hour through the use of a 4-gas meter, which revealed the concentrations of hydrogen cyanide, hydrogen sulfide, carbon monoxide, and percent oxygen. Instantaneous dust readings were also collected utilizing a personal DataRAM. These five readings were logged hourly into the field book. Every week this data, along with field notes, were used to write a letter to the client explaining the work performed, as well as explanations for any exceedances and what control measures were enforced to alleviate these exceedances.Fordham Univ
