General Information
Currently all routine analytical services allow for Contract Laboratory Program (CLP) laboratories to conduct modified analyses. Modified analyses that may be requested include, but are not limited to: adding additional compounds, adjusting Contract Required Quantitation Limits (CRQLs) for target analytes, and making minor adjustments to specific analytical protocols to enhance method performance. Performance of modified analyses by laboratories is voluntary. Laboratories should consult their contract for details regarding modified analyses.
Request Procedure
The regional requestor must submit a CLP Modification Request Form to the CLP Organic or Inorganic Program Manager (PM) at least two weeks prior to sampling. The request is to be made in writing (email) and must include the name of the site, approximate number of samples or duration of specific sampling events, projected sampling dates, and required modifications to the appropriate SOW. A separate request must be made for each site.

The CLP PM will review the request to ensure that the requested modification remains within the scope and intended purpose of the SOW. SMO will review and complete the section on bidding requirements. The PM will then generate the final modification request form, forward it to SMO, and send a copy to the requestor. SMO will process the request and then schedule with the appropriate laboratory.
