Air Toxic Data An Improved Tool for Air Emissions Data Collection - PowerPoint PPT Presentation

1 Air Toxic Data An Improved Tool for Air Emissions Data Collection Genesee Finger Lakes Chapter Joint Meeting of the AWMA & NYWEA February 14, 2017

2 Overview • AWMA Annual Meeting – State Programs • Air Contaminant vs Regulated Air Pollutant • Development of the “Barlow” Spreadsheet Boiler example • Asphalt Plant Template • • Air Compliance and Emissions (ACE) Electronic Reporting

3 AWMA Annual Meeting – June 2018 Air Toxic Monitoring • The use of cheaper and more accurate sensors and public and private entities collection of more ambient data on air toxics concentrations. • What do the results mean and what best practices exist? • Is the general public actively involved in any part of the process, and if so, how?  New York Community Air Screen Program Introduced in April 2012  Finger Lakes Zero Waste Coalition, Inc. 

Screen Program Community Air

5 Screening versus Monitoring • Screening  Air sampling on a limited basis  Used to determine whether area has an air quality concern  Samples can be collected in places and at times reflecting potentially higher pollutant concentrations • Monitoring  Air samples collected for longer period than screening, e.g. 6 months, 1 year  Implemented after screening suggests air quality concern  Sited following specific EPA criteria

6 Program Overview • EPA funded • Participation by application process  4 page application, available on-line  Applications scored using the following considerations: • Description of community concern • proximity to known sources and existing monitors • Prior citizen complaints

7 Program Specifics • Glass-lined SUMMA canisters • EPA’s TO-15 method, 43 air toxics • Quality assurance and quality control • 1-hr sample collection • Field log & chain of custody completed

8 Conveying Results and Risk • What are our goals?  Provide results and risk information in a meaningful and transparent manner Screening Comparison Graphs • Toxicological Trees • • What are our responsibilities?  Protect the environment and enhance health, safety and welfare of the people  Minimize unwarranted concern

11 Program Outcome - Communicating Results • Three levels of communication 1. Letter in plain English 2. Report detail Program Sampling  Analysis  Interpretation  Results  Discussion  Limitations  3. Appendices more detailed and technical Controlling Sources of Toxic Air Pollutants  Uses, Sources and Potential Exposure  Graphs comparing DEC air toxics network to community samples 

12 AWMA Annual Meeting – June 2018 State Programs • What risk assessment approaches are used to determine when pollution control or operating limits are added to permits? • How, and how often, are programs reviewed and updated? • What best practices exist to optimize public health protection and regulatory efficiency • How do states decide which pollutants are of interest?

13 How do states decide which pollutants are of interest? Air contaminant vs Regulated Air Pollutant (contaminant)  Regulated air pollutant or regulated air contaminant . (1) NO x and any VOCs; • (2) any air contaminant for which a NAAQS has been • promulgated; (3) any air contaminant that is subject to any NSPS or • NESHAP.  Air contaminant or air pollutant . A chemical, dust, compound, fume, gas, mist, odor, smoke, vapor, pollen or any combination thereof.

14 Development of Short-term & Annual Guideline Concentrations • American Council of Governmental Industrial Hygienists (ACGIH) • USEPA – Integrated Risk Information System (IRIS) • NYS Department of Health • NYS Department of Environmental Conservation  Contaminants with Short-term health effects: California’s OEHHA Table • ACGIH short-term and ceiling values •

15 NYS DEC’s (SGC/AGC) Tables Short-term and Annual Guideline Concentration AGCs 140 129 452 190 57 TLVs NYS DOH USEPA DEC Analogy

16 Toxic Substance Control Act (TSCA) • 23,000 “new chemicals” have been added to the TSCA inventory since its first establishment in 1979. • Several thousand chemicals are currently in use, and hundreds more are introduced to the market every year. • Due to the time and resource-intensive nature of chemical safety testing, only a small fraction of chemicals have been evaluated for potential health effects.

17 § 212-1.3 Determination of Environmental Rating • (a) Toxicity of the air contaminant; • (b) location of sensitive environmental receptors; • (c) emission dispersion characteristics taking into account relative to the surrounding buildings and terrain; and • (d) the projected maximum cumulative impact.

18 Evaluating “Unknown” Air Contaminants • Rule out High Toxicity based on definition in 212-1 • Structure Activity Relationships • Toxicity assigned a moderate classification  DAR-1 suggest starting with an initial Environmental Rating of “B”  Annual actual offsite concentration < 0.1 ug/m 3  Yearly actual emissions less than 100 pounds per year

19 What is the “Barlow” Spreadsheet • A method to organize emissions in one document • Components of the spreadsheet  Facility wide summation of emissions  Facility wide summations of predicted offsite concentrations  Access to SCCs, DEC emission statement codes and air contaminant database

20 Difference in Addressing Emissions Application Organization “Barlow” Spreadsheet • Facility • Facility • Emission Unit - • Emission Unit - Description Description  Process  Building  Emission Point  Emission Point Emission •  Emission Source/Control Source/Control Building •  Process

21 Facility Level Page (Tab) – Boiler Example • First, List all air contaminants at the facility.  All air contaminants that are currently listed with the State are included in the spreadsheet.  The listed air contaminants will be duplicated throughout the other tabs, Emission Unit level, Process level, etc.  Inputted data from processes will be summed on the facility page.

22

23 Process Level Page (Tab) – Boiler Example • Input the appropriate Source Classification Code (SCC) SCC listed on spreadsheet  • Input Process ID Input Annual Throughput – mm ft 3 , 10 3 gallons • • Input data based on Emission factors: lbs/gallon, lbs/ton of product, lbs/mmBtu, etc.. 

26 Emission Point Level Page (Tab) – Boiler Example • Enter processes associated with emission point • Spreadsheet allows for air dispersion modeling data to be inputted as maximum one-hour and annual concentrations. • SGC and AGCs are built into the spreadsheet and offsite concentration to SGC/AGC are shown.

27

28 Emission Unit Level Page (Tab) – Boiler Example • Data from the maximum emissions of the processes are summed to the Emission Unit level. • Data from the maximum concentrations of processes are summed to the Emission Unit level. • All Emission Units are summed at the Facility Level

30 Asphalt Plant Example • Standardized input screen Ton per year cap • • Emission factors Based on batch or drum plants • Fuel • Silo storage • Truck loadout • Hot oil heater •

32 Air Compliance and Emissions (ACE) Electronic Reporting

33 How to Get Enrolled in ACE • http://www.dec.ny.gov/chemical/54266.html • To use ACE, an Application for Electronic Reporting System must be completed, signed and notarized. • Once the application has been approved, the account holder will be emailed a statement of acceptance, specific information about their ACE account and user manuals.  Responsible Official (RO)  Emission Statement Editor (ESE)  Emission Statement Reviewer (ESR)

34 Benefits of ACE to End-Users • NYSDEC anticipates ACE to save time and resources for permittees and states while increasing data accuracy and improving compliance. • Reduce transcription errors. • The ability to upload previous year’s submission and only edit data where needed. • Report standardization • Imbedded QA checks

35 In Summary • New chemicals are being introduced into the marketplace annually. • “Lists are only good as of yesterday.” • NYSDEC and the regulated community need to work together to identify and address the emissions of these “new” air contaminants on the environment and the public. • A conservative approach is needed to evaluate the potential adverse effects of these contaminants until more data is available.
