The act of removing mold or hazardous materials from buildings. See also “Abatement”.
SPCC
Spill Prevention, Control, and Countermeasure. It is a system designed to provide instructions to companies that work with large amounts of oil. One gallon of oil spilled into water can contaminate up to one million gallons of water, which is why it is so important to have the right processes in place. All sites with …
Storm Water Management
The effort to reduce runoff of rainwater or melted snow into streets, lawns, and other sites and the improvement of water quality, according to the United States Environmental Protection Agency (EPA). https://www.epa.gov/water-research/storm-water-management-model-swmm
SWPPP
Storm Water Pollution Prevention Plan. The SWPPP is a document that outlines how a construction project will minimize storm water pollution. In Texas, nearly all construction site operators engaged in clearing, grading, excavation activities that disturb one acre or more, including smaller sites in a larger common plan of development or sale, are required to …
SWQMP
Storm Water Quality Management Plan. The SWQMP takes over where construction ends. Larger cities, such as Houston, Dallas, Fort Worth, San Antonio, and Austin require a SWQMP plan and permit to properly control runoff from sites. Most recognizable is the detention and retention ponds. These must be inspected regularly and maintained in order for permits …
Total Lead SW 846
Method of analysis to determine lead level, if any, in paint. Bulk samples are collected by a licensed Lead Inspector by scraping approximately 1” square off of a substrate. These samples are then analyzed by an accredited laboratory (NLLAP).
Toxicity Characteristic Leaching Procedure (TCLP)
A method of analysis for metals in samples taken as part of a lead abatement and is used to determine disposal method of the waste. It is a chemical analysis process used to determine whether there are hazardous elements present in a waste. The test involves a simulation of leaching through a landfill and can …
Transmission Electron Microscopy (TEM)
A method of analyzing air samples for asbestos. Samples are collected during abatement and analysis is completed by an accredited laboratory (NVLAP). An electron source at the top of the microscope emits electrons that travel through a vacuum in the column of the microscope. Electromagnetic lenses are used to focus the electrons into a very …
X-Ray Fluorescence (XRF)
A non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the chemistry of a sample by measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary X-ray source. Each of the elements present in a sample produces a set of characteristic fluorescent X-rays …
