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

• Discard sample bottles or sample lids that have been dropped onto the ground prior to samplecollection.• Not leave the cooler lid open for an extended period of time once samples are placed inside.• Not touch the exposed end of a sampling tube, if applicable.• Avoid allowing rainwater to drip from rain gear or other surfaces into sample bottles.• Not eat, smoke, or drink during sample collection.• Not sneeze or cough in the direction of an open sample bottle.• Minimize the exposure of the samples to direct sunlight, as sunlight may cause biochemicaltransformation of the sample to take place.• Decontaminate sampling equipment prior to sample collection using a TSP-soapy water wash, distilledwater rinse, and final rinse with distilled water.• Dispose of decontamination water/soaps appropriately; i.e., not discharge to the storm drain system orreceiving water.Immediately following collection, samples for field analysis will be tested in accordance with the fieldinstrument manufacturer’s instructions and results recorded on the Construction Site Monitoring Checklists,provided in Appendix F. Any samples provided to a lab will be provided within 48 hours and use only thesample bottle provided by the lab.Uncontaminated sample will be compared to the samples with potential contamination.For an initial verification of laboratory or field analysis, duplicate samples will be collected at a rate of 10percent or 1 duplicate per sampling event. The duplicate sample will be collected, handled, and analyzedusing the same protocols as primary samples, and will be collected where contaminants are likely, and not onthe upstream sample. A duplicate sample will be collected immediately after the primary sample has beencollected. Duplicate samples will not influence any evaluations or conclusions; however, they will be used as acheck on state certified laboratory quality assurance.Visible PollutantsGrab samples will be collected and preserved in accordance with the methods identified above. Onlypersonnel trained in proper water quality sampling will collect samples.Samples will not be collected directly from ponded, sluggish, or stagnant water. Samples will be collectedusing one of the following methods:• Placing a sample bottle directly into the collected flow in or near the main current upstream ofsampling personnel, and allowing the sample bottle to fill completely; OR,• Placing a decontaminated or ‘sterile’ bailer or other ‘sterile’ collection device in or near the maincurrent to collect the sample, and then transferring the collected water to appropriate sample bottles,allowing the sample bottles to fill completely. Run-on samples, if applicable, will be collected to identifypotential turbidity that originates off the project site and contributes to direct discharges from theconstruction site to the Santa Ynez River. Run-on samples will be collected down gradient and withinclose proximity of the point of run-on to the project by pooling or ponding water and allowing theponded water to spill over into sample bottles directly in the stream of water.Non-Visible PollutantsNon-visible pollutants may include those from:• Concrete Wastes (lighting foundations, concrete v-ditch and ADA curb ramp)• Vehicle fluids, including oil, grease, petroleum and coolants (from construction equipment)• Vehicle and equipment fueling• Sanitary Waste• Landscaping products• Soil stabilization productsMunicipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 19
