Shale-Gas Monitoring Update

Overview Preparations for the ‘next’ Shale-Gas Monitoring Report ‘Bean Counting’ Air Monitoring

Next Report

2014 Shale-Gas Monitoring Report High level of interest and anticipation. Comprehensive 15 Monitoring Values1. Infrastructure2. Flora (Plants)3. Forest Health4. Invasive Species5. Water6. Soil7. Air8. Incidents

9. Fauna (Wildlife)10. Recreation11. Community Engagement12. Timber13. Energy14. Revenue15. The Forest Landscape

Included data up to 2012 (with some from 2013).

2nd Shale-Gas Monitoring Report Interest and desire for another report. Timeline – 2017-18 timeframe for release. 4 years of new data from 2013-2016.

Expectations Comprehensive Current conditions Change (2014 report mostly ‘baseline’) Adaptive Management Lessons learned Management implications How ‘monitoring’ has influenced/informed guidelines/policies and on-

the-ground management

Report Design/Format Taking a very good report and making it better. Where we are as a bureau and a program. Emphasize adaptive management. Deviate from the 2014 ‘value based’ chapter format. Broad chapters that cover multiple values.

Enable to show overlap in values and discussion of values in context of adaptive management and other values.

Time Table January – March, 2017Compile data sets and prepare preliminary write-ups

of summaries and results. April – June, 2017Compile write-ups into chapters.

July 1, 2017Complete first draft.

July – ?Conduct internal reviews and prepare for

publication.

Status Compiling data sets (up to 2016) in process. Conducting analysis of data in process. Preparing preliminary summaries of results in

process.

Tentatively on target for chapter writing in April.

Air Quality Monitoring

Restek Dr. Jason Herrington Senior Air Innovations Chemist PhD – Environmental Studies, Chemistry

What Restek does:“Restek is a leading developer and manufacturer of chromatography products. We provide analysts around the world with the innovative tools they need to monitor the quality of air, water, soil, foods, pharmaceuticals, chemical, and petroleum products. We supply columns, standards, and accessories, manufactured under ISO 9001 certification and backed by the best service in the industry. From sample collection to preparation, from injection through separation to detection, build your liquid or gas chromatography solution with products and expertise from Restek.”

Canister Passive grab sample device. Smaller than a propane tank. Canister is a vacuum. Sample collection:

• Open valve for immediate/instantaneous sample.

• Equip with valve for timed sample collection (minutes, hours, days, whatever).

Canister Appropriate for VOC’s and ‘light

hydrocarbons’ such as ethane, butane, propane, etc.

‘Siltek® treatment is a proprietary process, developed by Restek Corporation, through which an inert layer is chemically bonded to a metal surface. The surface produced by this treatment is virtually inert to active compounds. The stainless steel pathway described in this guide is sufficient for sampling atmospheres containing only nonreactive compounds, but for reactive compounds the entire sampling pathway should be Siltek® treated to eliminate contact between the reactive analytes and the metal surfaces. Siltek® treatment can be applied to the interior surfaces of the canister and valve, to ensure an inert sample pathway.’

Thermal Desorption Unit Tubes Grab sample device. Active with pump or passive with diffusion cap.

About the size of a Sharpie. Packed with medium that captures ‘heavier’ constituents (PM2.5). Larger particles in diesel exhaust.

Applicability Canisters (of smaller size) will likely be

adequate for sampling air on well pads. Tubes will likely be adequate for

sampling air on compressor station pads.

A sampling design can be devised to obtain objective and credible information using these products.

Feasibility Easy to handle and use. Well within our scope of expertise. Set it out, open valve and wait. Ship to lab for analysis (30 to 90 days OK).

Analysis of constituents. Clean and reset canisters and tubes.

Sampling design – to do it right! Not necessarily just a one-off proposition. Multiple canisters – upwind, downwind and at point of

interest...height column. Multiple times of year (seasons), times of day and weather conditions. Multiple sites and multiple controls.

Time and cost prohibitive.

Conclusion Preparations for the next report have begun. Late 2017 – early 2018 target release date.

We have better, more refined data. Will result in discrepancies with figures in 2014 report.

Have investigated the incorporation of air quality monitoring into our program. Best if we work with experts in DEP Air Quality Section.
