1‐Hour SO2 NAAQS Implementation: Final Data Requirements Rule, Webinar Slides

This presentation helps air agencies understand how to meet requirements for reporting sulfur dioxide (SO2) concentrations in their ambient air, from identified emission sources.

Updated Guidance for Area Designations for the 2010 Primary Sulfur Dioxide (SO2) National Ambient Air Quality Standards (NAAQS)

The purpose of this memorandum is to provide information on the schedule and process for designating areas for the 2010 primary sulfur dioxide (SO2) national ambient air quality standard (NAAQS).

Findings of Failure to Submit State Implementation Plans (SIP) Required for Attainment of the 1-Hour Primary Sulfur Dioxide National Ambient Air Quality Standard (NAAQS) Fact Sheet

This page contains the 2016 fact sheet for the Findings of Failure to Submit State Implementation Plans (SIPs) for 2010 Sulfur Dioxide (SO2) Standard for 11 states.

Technical Assistance Documents for Implementing the 2010 Sulfur Dioxide Standard

These documents provide technical advice on the use of modeling and monitoring to determine if an area meets the 2010 SO2 National Ambient Air Quality Standard (NAAQS).

Applying or Implementing Sulfur Dioxide Standards

Along with developing the SO2 standards themselves (part of the National Ambient Air Quality Standards, or NAAQS), EPA also develops requirements for how to apply or implement them, and work toward about attaining and maintaining those standards.

Sulfur Dioxide State Implementation Plan (SIP) Checklist Guide

Tools, guidance, and examples to assist air quality agencies of non-attainment areas in developing plans to implement national ambient air quality standards (NAAQS), including the sulfur dioxide (SO2) air emissions standard.
