Applicable water quality standards means all water quality standards to which a discharge is subject under the federal Clean Water Act and which has been (a) approved or permitted to remain in effect by the Administrator following submission to the Administrator pursuant to Section 303(a) of the Act, or (b) promulgated by the Director pursuant to Section 303(b) or 303(c) of the Act, and standards promulgated under (APCEC) Regulation No. 2, as amended.
Biological safety cabinet means a containment unit suitable for the preparation of low to moderate risk agents where there is a need for protection of the product, personnel, and environment, according to National Sanitation Foundation (NSF) Standard 49.
Composite sample means a combination of individual samples of wastewater taken at 1 hour intervals, for eight (8) hours (or for the duration of discharge, whichever is less), to minimize the effect of variability of the individual samples. Individual samples must be of equal volume. (Example: one (1) liter per hour.)
Definite quantity contract means a fixed price contract that provides for a
Water quality standards means provisions of state or federal law which consist of a designated use or uses for the waters of the Commonwealth and water quality criteria for such waters based upon such uses. Water quality standards are to protect the public health or welfare, enhance the quality of water and serve the purposes of the State Water Control Law (§ 62.1-44.2 et seq. of the Code of Virginia) and the federal Clean Water Act (33 USC § 1251 et seq.).
Web Site Accessibility Standards/Specifications means standards contained in Title 1 Texas Administrative Code Chapter 206.
Nominal tomographic section thickness means the full width at half-maximum of the sensitivity profile taken at the center of the cross-sectional volume over which x-ray transmission data are collected.
Composite mortality tables means mortality tables with rates of mortality that do not distinguish between smokers and nonsmokers.
Radio frequency identification (RFID means an automatic identification and data capture technology comprising one or more reader/interrogators and one or more radio frequency transponders in which data transfer is achieved by means of suitably modulated inductive or radiating electromagnetic carriers.
Total resource cost test or "TRC test" means a standard that is met if, for an investment in energy efficiency or demand-response measures, the benefit-cost ratio is greater than one. The benefit-cost ratio is the ratio of the net present value of the total benefits of the program to the net present value of the total costs as calculated over the lifetime of the measures. A total resource cost test compares the sum of avoided electric utility costs, representing the benefits that accrue to the system and the participant in the delivery of those efficiency measures, as well as other quantifiable societal benefits, including avoided natural gas utility costs, to the sum of all incremental costs of end-use measures that are implemented due to the program (including both utility and participant contributions), plus costs to administer, deliver, and evaluate each demand-side program, to quantify the net savings obtained by substituting the demand-side program for supply resources. In calculating avoided costs of power and energy that an electric utility would otherwise have had to acquire, reasonable estimates shall be included of financial costs likely to be imposed by future regulations and legislation on emissions of greenhouse gases.
Web Site Accessibility Standards/Specifications means standards contained in Title 1 Texas Administrative Code Chapter 206.
Cubic foot of gas means the amount of gas required to fill a cubic foot of space when the gas is at an absolute pressure of fourteen and seventy-three hundredths (14.73) pounds per square inch at a temperature of sixty (60) degrees Fahrenheit.
Anti-Static Product means a product that is labeled to eliminate, prevent, or inhibit the accumulation of static electricity. “Anti-Static Product” does not include “Electronic Cleaner,” “Floor Polish or Wax,” “Floor Coating,” and products that meet the definition of “Aerosol Coating Product” or “Architectural Coating.”

Gallon means a United States gallon of two hundred thirty-one cubic inches of liquid at 60º Fahrenheit, and at the equivalent vapor pressure of the liquid.
Sewage sludge weight means the weight of sewage sludge, in dry U.S. tons, including admixtures such as liming materials or bulking agents. Monitoring frequencies for sewage sludge parameters are based on the reported sludge weight generated in a calendar year (use the most recent calendar year data when the NPDES permit is up for renewal).
Low-level radioactive waste or “waste” means radioactive material that consists of or contains class A, B, or C radioactive waste as defined by 10 C.F.R. 61.55, as in effect on January 26, 1983, but does not include waste or material that is any of the following:
Categorical pretreatment standard or "categorical standard" means any regulation containing pollutant discharge limits promulgated by the environmental protection agency in accordance with sections 307(b) and (c) of the Act (33 U.S.C. section 1317) that apply to a specific category of users and that appear in 40 CFR chapter I, subchapter N, parts 405 through 471.
health and safety specification means a site, activity or project specific document prepared by the client pertaining to all health and safety requirements related to construction work;
Process weight means the total weight of all materials introduced into any source operation. Solid fuels charged will be considered as part of the process weight, but liquid and gaseous fuels and combustion air will not.
Baseline data means information gathered at a selected point in time and used thereafter as a basis from which to monitor change.
