The purpose of Amendment 03 is to answer the following questions:

QUESTION: Please identify the specific USCG certification(s) required for technical acceptability.

ANSWER: USCG does not specify certifications required for technical acceptability; however, specifying the accreditations and certifications that the laboratory possess in the proposal would be acceptable.

QUESTION: Please provide the required analytical methods and acceptance limits for aspect, pH, conductivity, dissolved solids, and ash testing.

ANSWER: ASTM or ISO methods for each parameter are acceptable. Inspection limits are in Appendix A of Attachment 2 – Statement of Work – 70Z03826QB0000147.

QUESTION: Please confirm whether a small-business prime contractor may use a qualified subcontract laboratory to perform the testing.

ANSWER: A qualified subcontracted laboratory would be considered by USCG provided all requirements in the statement of work can be met.

QUESTION: Please specify the required sample volume, container type, preservation method, and maximum holding time for each analysis.

ANSWER: Sample containers will be provided by the contractor, thus volume and container type will be dictated by the laboratory. Currently, USCG procedures call for filling the entire container then placing bottle into Zip-Loc bag, then placing that into the prepaid shipping container. There is no specified maximum holding time; however, samples are usually shipped from the USCG facility within 24 hours.

ANSWER: Inspection limits are in Appendix A in Attachement 2 - Statement of Work - 70Z03826QB0000147.

QUESTION: If no specific methods are prescribed, may the laboratory use appropriate validated ASTM, ISO or Standard Methods, provided its reporting limits are below the applicable acceptance thresholds?

QUESTION: Does the required seven-day reporting period mean seven calendar days from laboratory receipt?

ANSWER: Yes. The reporting period is 7 calendar days from the date of receipt.
