1 Executive Summary National Grid (NGRID) retained ENVIRON International Corporation (ENVIRON) to conduct an industrial hygiene exposure assessment and air sampling during gas restoration work activities in the aftermath of Hurricane Sandy (October 29-30, 2012) that severely impacted the Northeastern United States (US). On November 10, 2012, Mr. Corey Briggs, CIH, CET, CIT of ENVIRON’s Boston office was contacted by Ms. Kathleen H. Smith, Director of Safety, Health, and Environment, to provide onsite industrial hygiene assessment and air sampling services for employees who were conducting work activities in the impacted areas of Brooklyn, Breezy Point, Long Island, Staten Island, and Roxbury. Mr. Briggs was informed that the assessment and sampling were going to be conducted to evaluate the risk of potential worker exposure to selected air contaminants of concern. With this in mind, and while developing the proposed sampling plan, ENVIRON and NGRID utilized existing information based upon Ms. Smith’s onsite observations, government recommendations on protecting responders after hurricanes and flood events, and industry knowledge of potential air contaminant hazards encountered during outdoor-related work, as well as response to water intrusion, to develop an initial scope of work to assess the most likely and hazardous air contaminant exposures. Deemed of most concern was work in areas where there was potential exposure to asbestos, respirable dust, and crystalline silica from hurricane debris piles, accumulated sand, construction/excavation work, vehicle movement, and demolition activities.
With respect to areas impacted by the extensive flooding, mold, bacteria, and other microbes were assumed to be present and employee protection was to be provided by a combination of administrative controls, management practices, the use of appropriate personal protective equipment, good personal hygiene, and prompt medical treatment of any cuts or puncture wounds. Also, with regard to the outdoor and intermittent indoor work activities, sampling for naturally-occurring microorganisms like bacteria and mold is not typically conducted due to the fact that 1) there are no established exposure levels/standards and 2) outdoor concentrations are typically utilized as the “normal background” for comparison purposes in indoor air quality studies and microbial investigation and remediation. Inorganic lead and polychlorinated biphenyls (PCBs) were also discussed but determined to be secondary concerns from an exposure standpoint due to the existing environmental conditions. If results from the initial respirable dust monitoring and sampling were of note, these materials would have been considered for evaluation.
After approval of the scope of work, ENVIRON began the process of conducting the industrial hygiene exposure assessment and air sampling during gas restoration work activities. Representatives from ENVIRON’s New England Business Unit mobilized to the site and conducted the industrial hygiene sampling and exposure assessment during gas restoration work activities from November 12- 20, 2012.ENVIRON’s assessment included both qualitative and quantitative assessments of gas restoration work activities in the most severely storm-impacted areas of Brooklyn, Breezy Point, Roxbury, Long Island and Staten Island. National Grid’s representatives indicated to ENVIRON that the gas restoration work that was to be conducted in these locations would represent a “worst case scenario” for the purposes of evaluating potential exposures of gas and electrical restoration personnel to the selected air contaminants.
2
At the request of NGRID, the assessment initially focused on the work activities conducted by employees in the Customer Meter Service (CMS) Department. On November 14, 2012, Mr. Chris Conlon, NGRID Director of Process Safety requested that employees in the Construction and Maintain (Construct/Maintain) Departments also be monitored. Although, ENVIRON was instructed to monitor only NGRID employees, due to the nature of the gas restoration work activities in wake of a catastrophic event, NGRID employees were not always available. Thus, with approval from onsite NGRID representatives, contractors performing similar NGRID CMS or Construct/Maintain type work, as well as consultants, were monitored.
ENVIRON’s assessment included the following tasks:
• Performing personal and area air sampling for Fibers (as Asbestos);
• Performing personal and area air sampling for Particulates Not Otherwise Classified - Respirable (PNOC-R), and Crystalline Silica (3 primary forms; quartz, tridymite, and cristobalite);
• Collecting real-time, direct-read measurements for respirable particulate and total volatile organic compounds (VOCs, as isobutylene) in the vicinity of the employee work activities. Please note that isobutylene is utilized as span gas for instrument calibration and as a reference for results; and
• Observing and documenting employee work activities and general work conditions in the impacted areas.
The personal and area air samples were collected during the sampling period for non-routine work activities. The results of the long-term and short-term personal air sampling were compared to the applicable Occupational Safety and Health Administration (OSHA) Permissible Exposure Limits (PELs).
Please note that area air samples were collected during our assessment and are typically used to screen a location or estimate a potential “worst case scenario” exposure event. They are typically not directly comparable to personal samples expressed as an eight-hour Time Weighted Average (8-hour TWA) and should not be used to show compliance with the OSHA PELs.
All sampling was conducted in accordance with the established industrial hygiene and industry best practices and standards and with ENVIRON’s November 10, 2012 proposal sent via email, and attached as Appendix E.

Results, Conclusions, and Recommendations
The results of the assessment along with our recommendations (in italics) are provided below. Please note that sampling results are representative of potential personal exposures on the particular day of sampling and reflect employee activities and operations. Also, please note that variations in equipment/process not in use, shift duties, length of the shift and tasks, etc. can affect exposure concentrations; in some cases, the personnel were working between 12 and 16 hour shifts in areas hardest hit by the storm.
As instructed by NGRID, ENVIRON has provided Microsoft Excel summary worksheets with detailed employee work activities and summary results. A short photo log has also been provided to document general work conditions. Real-time, direct-read respirable particulate measurements have also been provided.
Overall, none of the one hundred twenty one (121) area and personal samples collected between November 12 and November 20, 2012 in the hardest hit areas of the storm exceeded the OSHA Permissible Exposure Limits (PELs). Thus, respiratory protection would not have been required. ENVIRON was told that the employees who participated in the air sampling survey were to follow the applicable control measures (e.g. personal protective equipment [PPE]) as described in the “Safety Bulletin” and applicable safety and health protocols provided by the NGRID Safety, Environmental, and Health Department.
• All of the results of long-term (8 hour TWA) and short-term/excursion limit (30-minute) personal air sampling for Fibers (as Asbestos) were less than the OSHA PEL.
• The airborne concentrations of respirable particulate and crystalline silica for all of the 37 samples collected during the sampling survey were below the OSHA PEL-TWA of 5 mg/m3. The airborne concentration of 1 of the 37 samples in the Breezy Point area on November 19, 2012 was1.8 mg/m3 as an 8 hour TWA and approached the “calculated”* OSHA PEL-TWA of 2.4 mg/m3.
*There is not one crystalline silica exposure limit for all cases. Rather, the limit is derived from a calculation that takes into account the percentage of quartz, cristobalite, tridymite, and respirable dust specific to the particular work-site. When a percentage of quartz, cristobalite or tridymite is detected in a sample, a specific OSHA calculation is used to derive the sample specific PEL which is then compared to the specific exposure.
• The maximum real-time, direct-read measurement for respirable particulate was approximately 1.15 mg/m3 in an area of moderate sand coating and high vehicle traffic in the Rockaway West area of Long Island. From a “general comparison standpoint” since it is a real-time measurement and not a long-term personal air sample collected in the worker’s breathing zone, this airborne concentration is well below the OSHA PEL-TWA of 5 mg/m3 for respirable particulate.
• The results of the real-time, direct-read measurements for total volatile organic compounds, as isobutylene (TVOC) were “non-detectable”. The direct-read measurements collected by ENVIRON were as requested “spot checks” conducted during work activities in the various indoor basement locations for the employees being monitored (e.g., in response to reported odors)

Notify the affected National Grid employees and contract employees who participated in the study of the air sampling results in accordance with the provisions of the OSHA Standard 29 CFR 1910.1020, 1910.1001 and 1926.1101, and your internal employee exposure information notification practices. ENVIRON has provided Microsoft Excel summary worksheets with detailed employee work activities and results, employee notification forms which can be posted or distributed to employees and/or contractors who participated in the assessment.
The remainder of the report contains the details of the assessment, the list of Microsoft Excel tables that have been provided, and applicable appendices.

Of most concern, was work in areas where there was potential exposure to asbestos, respirable dust, and crystalline silica from hurricane debris piles, accumulated sand, construction/excavation work, vehicle movement, and demolition activities.
With respect to areas impacted by the extensive flooding, mold, bacteria, and other microbes were assumed to be present and employee protection was to be provided by a combination of administrative controls, management practices, the use of appropriate personal protective equipment, good personal hygiene, and prompt medical treatment of any cuts or puncture wounds. Also, with regard to the outdoor and intermittent indoor work activities, sampling for naturally-occurring microorganisms like bacteria and mold is no typically conducted due to the fact that 1) there are no established exposure levels/standards and 2) outdoor concentrations are typically utilized as the “normal background” for comparison purposes in indoor air quality studies and microbial investigation and remediation. Inorganic lead and polychlorinated biphenyls (PCBs) were also discussed but determined to be secondary concerns from an exposure standpoint due to the existing environmental conditions. If results from the initial respirable dust monitoring and sampling were of note, these materials would have been considered for evaluation.
Ms. Kerry Ann Jaggassar, MS and Ms. Amber Stangroom, BS of ENVIRON’s New England Business Unit met Ms. Smith on November 11, 2012 and along with Mr. Chris James who joined the team on November 12, 2012 conducted the industrial hygiene sampling survey and exposure assessment during gas restoration work activities from November 12- 20, 2012.
ENVIRON’s assessment included both quantitative and qualitative assessments of gas restoration work activities in the most severely storm-impacted areas of Brooklyn, Breezy Point, Roxbury, Long Island and Staten Island. National Grid’s representatives indicated to ENVIRON that the gas restoration work that was to be conducted in these locations would represent a “worst case scenario” for the purposes of evaluating potential exposures of gas and electrical restoration personnel to the selected air contaminants.

The personal and area air samples were collected during the sampling period for routine work activities conducted under abnormal work conditions. All long-term and short-term personal air sampling results were compared to the applicable Occupational Safety and Health Administration (OSHA) Permissible Exposure Limits (PELs).
Please note that area air samples were also collected during our assessment and are typically used to screen a location or estimate a potential “worst case scenario” exposure event. They are typically not directly comparable to personal samples expressed as an eight-hour Time Weighted Average (8-hour TWA) and should not be used to show compliance with the OSHA PELs.

3 Standard and Guidelines 3.1 Personal and Area Air Sampling
The following is a summary of the standards and guidelines used for ENVIRON's industrial hygiene assessment, results, interpretations, and recommendations.
The Occupational Safety and Health Administration (OSHA) has set forth general industry and construction standards (29 CFR 1910 and 1926) that identify maximum 8-hour time weighted averages (TWA) exposure limits, instantaneous ceiling exposure limits (C) and/or 15-minute short-term exposure limits (STEL) for specific airborne contaminants. These occupational exposure limits are referred to as OSHA's Permissible Exposure Limits (PELs) and are located in 29 CFR 1910.1000 and 29 CFR 1926 Subpart Z.
Substance-specific standards (e.g. PEL-TWAs and Excursion Limits) also exist for asbestos and are referenced in 29 CFR 1910.1001 and 29 CFR 1926.1101.
For respirable particulate and crystalline silica, a specific OSHA calculation is used to derive a PEL, which is then compared to the specific exposure. Details for the silica calculation using the OSHA eTool are provided in Appendix C.
Please note that area samples were collected during this assessment and are used to screen a location or estimate a potential worst-case scenario exposure event. They are typically not directly comparable to personal samples expressed as an 8-hour TWA and should not be used to show compliance with the OSHA PEL.
The OSHA Permissible Exposure Limits referred to in this report are summarized in tabular format in the attached Microsoft Excel worksheets listed under the tab ”Permissible Exposure Limit”.

4 Sampling, Analysis, and Monitoring Methods Prior to conducting the assessment, ENVIRON worked with Ms. Smith to develop the initial sampling and monitoring plan. The air contaminants of concern were identified based on initial discussions, descriptions of proposed work tasks, and available information regarding conditions in work areas as provided by Ms. Smith, as well as concerns expressed by workers. The initial work plan included air contaminants of concern believed to pose the largest exposure risk to personnel. The rationalization of the sampling plan is presented in Table 1.
Table 1: Sampling Plan Rationalization
Contaminant Methodology Rationale
Asbestos
NIOSH 7400 : Asbestos and other Fibers by Phase Contrast Microscopy (PCM)
Asbestos is an OSHA regulated substance and an overall employee exposure concern to NGRID. The risk of secondary exposure to NGRID employees due to demolition activities in adjacent work area (e.g. citizens removing debris from homes) needed to be evaluated along with NY Department of Sanitation removal of debris from roadways in vicinity of NGRID and contractor work activities; From a community exposure standpoint, the New York City Department of Environmental Protection had previously conducted area monitoring for potential asbestos at debris piles. Personal and area air sampling was conducted for comparison to calculated OSHA PELs. Analysis by PCM identifies total fiber count and thus further analysis by TEM was used to identify/confirm if asbestos fibers were present.
NIOSH 7402: Asbestos by Transmission Electron Microscopy (TEM)
9
Contaminant Methodology Rationale
Crystalline Silica (Quartz, Tridymite, and Cristobalite)
Modified NIOSH 7500/ OSHA ID-142:
Exposure risk due to environmental conditions in work areas such as, proximity to ocean front and large piles of sand, high traffic on roadways with heavy coating of sand (e.g., NY Department of Sanitation trucks and other vehicles); Potential exposure to Construct/Maintain employees who were drilling through concrete and/or asphalt to access subsurface lines. Personal air sampling was conducted for comparison to calculated OSHA PELs.
Respirable Particulate
Personal Air Sampling/ NIOSH 0600
Exposure risk due to movement of debris by home owners, relief organizations, high traffic roadways heavily coated with sand, drying flood conditions, etc.; Personal air sampling was conducted for comparison to OSHA PEL-TWA. The New York State Department of Environmental Protection also was conducting area air monitoring. Direct-read, real-time measurements used as a screening tool to assist in initial evaluations Periodic and intermittent dust conditions can be better evaluated measured with direct- read real-time instruments to give a “snap shot” of current conditions.
Area Sampling/ Direct-Read Real-Time measurements
10
Contaminant Methodology Rationale
Carbon Monoxide (CO), Hydrogen Sulfide (H2S), and Oxygen (O2), Flammable and combustible gases/vapors as a % of the Lower Explosive Limit (LEL)
Real time, Direct- Read [Multi-gas meter with a Photo-ionization detector (PID)]
Potential presence due to gas leaks, misuse of home generators, possible chemical spills in flooded basements, etc. These instruments were used where deemed appropriate and requested. Measurements were recorded if concerns regarding “chemical-type” odors were expressed by the employees being monitored.
Total Volatile Organic Compounds (TVOCs)
Mold N/A
Although molds and bacteria were obviously present, there are no methods for performing personal air sampling (especially for a mobile work force); ENVIRON was informed that PPE was available for NGRID employee use. With regard to the outdoor and intermittent indoor work activities, sampling for naturally-occurring microorganisms like bacteria and mold is not typically conducted due to the fact that 1) there are no established exposure levels/standards and 2) outdoor concentrations are typically utilized as the “normal background” for comparison purposes in indoor air quality studies and microbial investigation and remediation.
11
Contaminant Methodology Rationale
Lead N/A
Since it is naturally occurring in soil and has been historically introduced by deposition of lead gas emissions, etc., it was not deemed of importance due to the wet conditions that reduced the potential for exposure. If real-time measurements for respirable dust had detected from initial screenings, lead sampling would have been considered.
Polychlorinated Biphenyls (PCBs) N/A
If PCB contamination were present, it would likely be very localized rather than widespread; sampling methods difficult for a mobile work force (additional pump with filter and tube in series) could create hindrance for employee to safely complete his work task; sampling and analysis is very costly and time consuming; If real-time measurements for respirable dust had detected from initial screening, PCB sampling would have been considered.
Based on the available information available on November 10, 2012, NGRID and ENVIRON developed a sampling and monitoring plan (see Appendix E) which was implemented from November 12-20, 2012 primarily during daytime work activities. ENVIRON was told that NGRID employees were to follow the applicable safety and health protocols as published by the NGRID Safety, Environmental, and Health Department. Table 2 on the next page of the report summarizes the sampling activities conducted during the assessment.

4.1 Personal and Area Air Sampling
All long-term and short-term personal air samples were collected within the worker’s breathing zone. Both long and short-term personal air samples and area air samples were collected using battery-powered, personal air-sampling pumps (e.g., SKC, MSA, etc.) that drew air at a constant flow rate. Each pump was calibrated before and after sampling using a Bios Defender™ primary calibrator. Due to extreme limitations with regard to accessing AC power, high-volume air sampling could not be conducted.
The following OSHA and NIOSH sampling and analytical methods were used during this project:
• NIOSH 7400 : Asbestos and other Fibers by Phase Contrast Microscopy (PCM) • NIOSH 7402: Asbestos by Transmission Electron Microscopy (TEM) • NIOSH 0600/7500: Modified OSHA ID-142: Particulates not Otherwise Classified
(NOC), Respirable Particulate and Crystalline Silica Field blanks for each of the analytes were submitted to the laboratory for quality control purposes.
All samples and sample blanks for Fibers (as Asbestos) collected during this survey were hand-delivered under Chain of Custody for various levels of expedited analysis to EMSL Analytical, Inc. in Carle Place, New York, an American Industrial Hygiene Association (AIHA) accredited laboratory.
All samples and sample blanks for respirable particulate and crystalline silica collected during this survey were sent under Chain of Custody for various levels of expedited analysis to Galson Laboratories in East Syracuse, New York an American Industrial Hygiene Association (AIHA) accredited laboratory.
4.2 Real-Time, Direct-Reading Instrumentation Measurements
Real-time, direct-read measurements were collected using various meters during indoor and outdoor gas restoration work activities at the various locations.
Area measurements for airborne respirable particulate were collected using calibrated and field zeroed portable real-time aerosol monitors (e.g. Thermo personal DataRAM Model PDR-1000AN and the TSI DustTrak Model 8520).
Since odors were periodically reported by personnel inside of buildings, real-time, direct-read area measurements for total volatile organic compounds were also collected using a calibrated Rae Systems MultiRAE “plus” to determine any potential exposure to volatile organic compounds, as isobutylene. Please note that isobutylene is utilized as span gas for instrument calibration and as a reference for results.

5 Results, Conclusions, and Recommendations The results of the assessment along with our recommendations (in italics) are provided below. Please note that sampling results are representative of potential personal exposures on the particular day of sampling and reflect employee activities and operations. Also, please note that variations in equipment/process not in use, shift duties, length of the shift and tasks, etc. can affect exposure concentrations; in some cases, the personnel were working between 12 and 16 hour shifts in areas hardest hit by the storm. As instructed by NGRID, ENVIRON has provided Microsoft Excel summary worksheets with detailed employee work activities and summary results. A short photo log has also been provided to document general work conditions. Real-time, direct-read respirable particulate measurements have also been provided. Overall, none of the one hundred twenty one (121) area and personal samples collected between November 12 and November 20, 2012 in the hardest hit areas of the storm exceeded the OSHA Permissible Exposure Limits (PELs). Thus, respiratory protection would not have been required. ENVIRON was told that the employees who participated in the air sampling survey were to follow the applicable control measures (e.g. personal protective equipment [PPE]) as described in the “Safety Bulletin” and applicable safety and health protocols provided by the NGRID Safety, Environmental, and Health Department.
• All of the results of long-term (8 hour TWA) and short-term/excursion limit (30-minute) personal air sampling for Fibers (as Asbestos) were less than the OSHA PEL.
• The airborne concentrations of respirable particulate and crystalline silica for all of the 37 samples collected during the sampling survey were below the OSHA PEL-TWA of 5 mg/m3. The airborne concentration of 1 of the 37 samples in the Breezy Point area on November 19, 2012 was1.8 mg/m3 as an 8 hour TWA and approached the “calculated”* OSHA PEL-TWA of 2.4 mg/m3.
*There is not one crystalline silica exposure limit for all cases. Rather, the limit is derived from a calculation that takes into account the percentage of quartz, cristobalite, tridymite, and respirable dust specific to the particular work-site. When a percentage of quartz, cristobalite or tridymite is detected in a sample, a specific OSHA calculation is used to derive the sample specific PEL which is then compared to the specific exposure.
• The maximum real-time, direct-read measurement for respirable particulate was approximately 1.15 mg/m3 in an area of moderate sand coating and high vehicle traffic in the Rockaway West area of Long Island. From a “general comparison standpoint” since it is a real-time measurement and not a long-term personal air sample collected in the worker’s breathing zone, this airborne concentration is well below the OSHA PEL-TWA of 5 mg/m3 for respirable particulate.
• The results of the real-time, direct-read measurements for total volatile organic compounds, as isobutylene (TVOC) were “non-detectable”. The direct-read measurements collected by ENVIRON were as requested “spot checks” conducted during work activities in the various indoor basement locations for the employees being monitored (e.g., in response to reported odors)

Unless otherwise noted below, all quality control results associated with the samples were within established control limits.
Unrounded results are carried through the calculations that yield the final result and the final result is rounded to the number of significant figures appropriate to the accuracy of the analytical method. Please note that results appearing in the columns preceeding the final result column may have been rounded in order to fit the report format and therefore, if carried through the calculations, may not yield an identical final result to the one reported.
The stated LOQs for each analyte represent the demonstrated LOQ concentrations prior to correction for desorption efficiency (if applicable).
Unless otherwise noted below, reported results have not been blank corrected for any field blank or method blank.

Comparing Your Exposure to OSHA's Limit
Finding and comparing the actual exposure and the permissible limit will let you know if you need to take
action to protect against a silica hazard.
There is not one crystalline silica exposure limit for all cases. Rather, the limit is derived from a calculation that takes into account the percentage of quartz, cristobalite, tridymite, and respirable dust specific to your particular work-site. To determine the limit and compare it to the actual amount, you can:
Follow a written example to make the calculations yourself or
Let the Advisor Genius do the calculations for you You will supply certain data and the Genius will make some calculations to produce three different number:
The Genius performs calculations for a respirable dust sample. If your sample is collected as a total dust sample, you will need to make adjustments to the PEL and Severity the Genius calculates.
Apply Your Knowledge
There are also limits on coal dust and amorphous silica.
Continue with Taking Action to Protect Against Silica >>
PEL This number is the calculated permissible exposure limit for dust to which the worker may be exposed. It uses the data you supplied and is based on the percent crystalline silica in the sample. For example: 1.6 mg/m3
Exposure This number is the actual amount of dust that is in your work environment, for example: 4.8 mg/m3
Severity This number is derived by dividing the exposure by the PEL, for example: 4.8 / 1.6 = 3.0 If the severity number is higher than 1.0 you are above the limit. If the severity number is less than 1.0 you are below the limit.
Permissible Exposure Limit for Crystalline Silica
OSHA regulation 29 CFR 1910.1000 Table Z-3 is used to determine the exposure limits for crystalline silica. Though this regulation is under the General Industry Standard, crystalline silica exposures in the Construction and Maritime Industries are subject to this same limit. Regulating these industries under the General Industry Standard is specifically addressed in Appendix E of the OSHA Special Emphasis Program (SEP) for Silicosis.

EMAIL EXERPT: ENVIRON PROPOSED SAMPLING PLAN (Sent via email on 11/10/12)
Subject: Exposure Assessment and Personal Air Sampling - Post Hurricane Work in Long Island
Karen and Kathy: Sorry for the delay…I am on mini holiday in southern Virginia. I did speak with Kathy about ½ hour ago and she gave me an overview of the situation with your Customer Meter Service Representatives (approximately 400) that are going door to door in various locations in Long Island that have been hit by the Super Storm and are now working in remediation type conditions (debris of all types) After obtaining Kathy’s background information, we would propose the following proposed sampling plan for the next couple of days
Full shift personal samples for asbestos
Full shift personal air samples for respirable dust and the 3 primary crystalline silicas I’m not sure if fiberglass is a big issue are not since I am assuming that it is wet. Please let us know if you would like this addressed. It actually may be able to be analyzed with the asbestos. Although molds and bacteria are obviously present, there are no real methods for personal air sampling (especially for a mobile work force) and since Kathy mentioned that folks are wearing or encouraged to use N95 masks that is probably the best course of action. PPE such as disposable Tyvek suits, disposable gloves and having some form of sanitizing wipes or bottled water/soap/paper towel to clean up after each visit is also highly recommended assuming this equipment is advisable. Our crew would also be able to possibly bring some real time respirable dust monitor so that they could periodically check area levels where folks are working. Based upon the information provided, I have contacted KerryAnn Jaggassar my prime associate (who was outsourced to NGrid for several years and has done work in Long Island) who is now contacting other consultants in our area on their availability. The plan would be for them to mobilize early tomorrow morning to Long Island (probably driving in 1-2 cars) and meet Kathy or her designee at a designated location by approximately 11-am till noon. Or if Kathy can provide points of contact in advance, they could meet representatives at other specified locations. They could then begin meet up with personnel at various locations and disperse the sampling equipment. The hope would be to get air sampling done on Sunday afternoon/evening and Monday and Tuesday if needed. Kathy indicated that the representatives work may be done by then. Our crew can mobilize with 5 sampling pumps and cyclones and some media immediately. But I have contacted Galson laboratories who can ship media and sampling equipment today (via commercial air carrier) to a sister lab (Accutest) in Dayton, NJ who could then meet our team on the road to provide an additional pre-calibrated 25 sampling pumps (that would give us 30 total) and cyclones and media. We would hope to be able to sample at least 40 representatives during this time period which is approximately 10% of the impacted populations. As discussed with Kathy we would be focusing our sampling on the members of the various unions in the area. All work would be conducted on a time and materials basis. Since NGrid already has an account with Galson..we could either have you invoiced directly or it can be handled by us. We will work with you to determine how expediently you want laboratory analysis turnaround time. All work would be conducted in accordance with our existing Terms and Conditions in the MSA.
In order to authorize us proceed please contact me ASAP at 617-259-0172 since I need to get our order into Galson by 4pm at the very latest to get equipment shipped. Please contact me with any questions via cell.
