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.

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

  • 4 page application, available on-line
  • Applications scored using the following

considerations:

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?

How do states decide which pollutants are of interest?

Air contaminant vs Regulated Air Pollutant (contaminant)

  • Regulated air pollutant or regulated air contaminant.
  • (1) NOx 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.

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

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.

§ 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.

slide-18
SLIDE 18

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/m3
  • Yearly actual emissions less than 100 pounds per

year

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

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.

Process Level Page (Tab) – Boiler Example

  • Input the appropriate Source Classification Code (SCC)
  • SCC listed on spreadsheet
  • Input Process ID
  • Input Annual Throughput – mm ft3, 103 gallons
  • Input data based on Emission factors:
  • lbs/gallon, lbs/ton of product, lbs/mmBtu, etc..

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.

summed to the Emission Unit level.

  • All Emission Units are summed at the Facility Level

Air Compliance and Emissions (ACE) Electronic Reporting

slide-33
SLIDE 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)

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

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.
