Storm Water Pollution Prevention Plan (SWPPP) - the City of Lompoc!

In the event that sampling is needed, all non-storm water sample analyses will be sent to a state certifiedlaboratory. Use Appendix H as a guide.Sample Documentation ProceduresAll original data documented on sample bottle identification labels, Chain of Custody forms, Sampling ActivityLogs, and Inspection Checklists will be recorded using waterproof ink. These will be considered accountabledocuments. If an error is made on an accountable document, the individual will make corrections by liningthrough the error and entering the correct information. The erroneous information will not be obliterated. Allcorrections will be initialed and dated. Copies of the Construction Site Monitoring Checklists are provided inAppendix F.Sampling and field analysis activities will be documented using the following:• Sample Bottle Identification Labels: Sampling personnel will attach an identification label to eachsample bottle. At a minimum, the following information will be recorded on the label, as appropriate:– Project name– Project number– Unique sample identification number and location.[Project Number]-[Six digit sample collection date]-[Location](Example: 0G5304-081801-Upstream).Quality assurance/quality control (QA/QC) samples shall be identifiedsimilarly using a unique sample number or designation(Example: 0G5304-081801-DUP1).– Collection date/time (No time applied to QA/QC samples)– Analysis constituent• Sampling Activity Logs: A log of sampling events will identify:– Sampling date– Separate times for sample collection of upstream, downstream, run-on, and QA/QC samplesrecorded to the nearest minute– Unique sample identification number and location– Analysis constituent– Names of sampling personnel– Weather conditions (including precipitation amount)– Field analysis results– Other pertinent data• Chain of Custody (COC) forms: All samples to be analyzed by a state certified laboratory will beaccompanied by a COC form provided by the laboratory. Only the sample collectors will sign the COCform over to the lab. COC procedures will be strictly adhered to for QA/QC purposes.• Storm Water Quality Construction Inspection Checklists: When applicable, theContractor’s storm water inspector will document on the checklist that samples forsedimentation/siltation and/or turbidity were taken during a rain event.Ensure that all laboratory analyses are conducted according to test procedures under 40 CFR Part 136, unlessother test procedures have been specified and approved.4.6 Reporting Requirements and Records RetentionRecords of all monitoring inspections are required to remain onsite during the construction period and for aminimum of three years. All field and lab analyses results shall be kept in the SWPPP document.Records shall include the following items:• The date, place, and time of facility inspections, sampling, visual observations (inspections), and/ormeasurements, including precipitation;• The individual(s) who performed the facility inspections, sampling, visual observation (inspections),and/or measurements;• The date and approximate time of analyses;• The individual(s) who performed the analyses;Municipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 20
