REVISION OF THE NADP/NTN QUALITY ASSURANCE PLAN

Summary of mayor revisions in NADP QA Plan

Executive Summary:

Chapter 1: Overview of Quality Assurance Program

DEFINITION OF THE REMEDIAL ACTION PLAN:

The Remedial Action Plan describes the sequence of actions taken to resolve problems of noncompliance with NADP procedures, protocols, and criteria. The plan applies to violations of sampling protocols and siting criteria by established sites, unacceptable laboratory and data management procedures, and a site's failure to participate in QA programs.

REVISION OF THE NADP REMEDIAL ACTION PLAN:

Proposal on Revisions to the Remedial Action Plan:

1. CAL should continue to make decisions on operation issues and code samples accordingly (SP code) and enter it into the database. Or for example, CAL has given sites an exception for not doing field chemistry or having their collectors painted a different color.

Are their other sampling protocol that CAL gives an exception to without the sample being invalidated?

Do we want to give CAL the of official authority to grant these exceptions, which are considered to be chronic performance problems, since they have unofficially been handling them? This will reflect how remedial action is actually accomplished in the network

Re: Siting Criteria violations are not currently documented in the database. It is not appropriate to invalidate samples because of siting violations since it is unclear how these deviations effect the site's data quality.

2. CO Site Liaison will try to resolve chronic siting criteria violations for 6 months after notification of the violation with the site operator and site sponsor at established sites. If it remains unresolved then the violation is documented in the database.

3. We accept the pending exceptions and document them in the database

4. As conditions change at established sites, noted by Site Visitation Reports or correspondence with the Site Liaisons, these changes will be documented in the database.

5. A new data product will be made available to the data users to allow them to use these deviations from the NADP Siting Criteria for research on their effects on the data quality. This will not be an inclusive database but will include the current pending violations and those discovered in future Site Visitation reports and Site Liaison correspondence.
