Restructuring EPA’s Stationary Source Audit Program (SSAP)

Allowing Private Providers to Supply Audit Samples


Why did we have an audit program

Why Did We Have an Audit Program?

  • Audit samples provide assurance that testing performance was within acceptable limits during the compliance test

  • Many of the test methods in Part 60 (NSPS) require testers to measure an audit sample during a compliance test

  • There is a general requirement in Part 63 (NESHAPS/MACT) to analyze an audit sample during a compliance test


How did the ssap work

How Did the SSAP Work?

  • Audit samples were ordered by registered users through the SSAP database

  • Samples were shipped to the user or to an address specified by the user

  • The tester performing the compliance test measured the audit sample according to the enclosed directions and reports the results to the user


How did the ssap work1

How Did the SSAP Work?

  • The user reported the result to the database and got immediate pass/fail results

  • Users have access to historical results stored in the database


Why did epa restructure the ssap

To ensure the long term stability of the program

To allow the program to grow

By increasing the methods for which samples are available

By increasing the types of samples that are available – gases instead of liquid ampoules

Why Did EPA Restructure the SSAP?


How did epa restructure the program

Allow private providers to supply audit samples directly to the regulated sources

Require sources to buy the audit samples

How Did EPA Restructure the Program?


How did epa change its rules to allow private sample providers

How Did EPA Change Its Rules to Allow Private Sample Providers?

  • Amend the General Provisions of Parts 51, 60, 61, and 63 to state that audit samples will be available from private providers and not from EPA

  • Require sample providers to develop standard operating procedures through a consensus process

  • Require that sample providers be accredited by an independent accrediting body


Epa audit rule requirements

EPA Audit Rule Requirements

  • Sources required to purchase audit samples if commercially available

  • “Commercially Available” means that two or more independent Accredited Audit Sample Providers (AASPs) have audit samples available for purchase

  • Methods exempt from Audit samples: 3A, 3C, 7E, 6C, 7E, 9, 10, 18, 19, 20, 22, 25a, 303, 318, 321

EPA Audit Rule Requirements (cont)

  • One audit sample is required for each method used during a compliance test

  • Provide the opportunity for the compliance authority to comment on the selected concentration level for the audit

  • Source reports results to AASP

  • Pass/fail results reported to Regulatory Agency and Source at same time


Epa audit rule requirements cont1

EPA Audit Rule Requirements (cont)

  • The acceptance limit shall be set so that there is a 95 percent confidence that 90 percent of well qualified labs will produce results within the acceptance range
