899 DEFINITIONS AND ABBREVIATIONS

899.1 When used in this chapter, the following terms shall have the meanings ascribed:

Asbestos abatement - the removal, encapsulation, enclosure, disposal, or transportation of asbestos or material that contains asbestos.

Asbestos worker - a person who is engaged in asbestos abatement.

Business entity - a partnership, firm, association, corporation, or sole proprietorship that is engaged in asbestos abatement.

Emergency renovation operation - a renovation operation that was not planned but results from a sudden, unexpected event that, if not immediately attended to, presents a safety or public health hazard, is necessary to protect equipment from damage, or is necessary to avoid imposing an unreasonable financial burden. This term includes operations necessitated by non-routine failures of equipment.

Encapsulate - the coating, binding, or resurfacing of a wall, ceiling, pipe, or other structure to prevent friable asbestos or material that contains asbestos from becoming airborne.

High-efficiency particulate air (HEPA) filter - a filter capable of trapping and retaining at least ninety-nine and ninety-seven hundredths percent (99.97%) of all monodispersed particles three tenths (0.3) micrometers ([mu] m) in diameter or larger.

Negative pressure system - equipment that ensures that the static pressure in an enclosed work area is lower than that of the environment outside the containment barriers.

Person - an individual or non-business entity, including a District of Columbia government employee.

899.2 When used in this chapter, the following abbreviations shall have the meanings ascribed:

RACM - Regulated asbestos-containing material

APPENDIX 8-1

EMISSION LIMITS FOR NITROGEN OXIDE

Emission limits for nitrogen oxide in fossil-fuel-fired steam generating units of more than one hundred million (100,000,000) British Thermal Units (BTU.) per hour heat input are as follows:

1. (a) Two tenths (0.2) lb. per million BTU heat input (0.36 g. per million cal.) maximum two (2) hour average, expressed in NO2, when gaseous fossil fuel is burned;
2. (b) Three tenths (0.3) lb. per million BTU heat input (0.54 g. per million cal.) maximum two (2) hour average, express as NO2, when liquid fossil fuel is burned;
3. (c) Seven tenths (0.7) lb. per million BTU heat input (1.26 g. per million cal.) maximum two (2) hour average, expressed NO2, when solid fossil fuel (except lignite) is burned; and
4. (d) When different fossil fuels are burned simultaneously in any combination the

applicable standard shall be determined by proration, according to the following formula:

$$\frac{x(0.2)+y(0.3)+z(0.7)}{x+y+z}$$

x is the percent of total heat input derived from gaseous fossil fuel;

y is the percent of total heat input derived from liquid fossil fuel; and

z is the percent of total heat input derived from solid fossil fuel.
