and the limit is 20%. In addition, the sum of all three
categories may not exceed 20% by volume. The rule,
known originally as Rule 66 was promulgated in 1967
in Los Angeles, CA, and is roughly based on smog
chamber testing. Aromatics and branched ketones
have been strongly affected by the Rule 66 approach.
This definition is now contained in Rule 102 of the
South Coast Air Quality Management District. The
photochemically reactivity concept has been largely
supplanted by the VOC concept in regulations.
Prevention of Significant Deterioration (PSD):
A program established to preserve air quality in areas
already meeting the NAAQS.
Proposition 65:
Formerly known as the California Safe drinking Water
and Toxic Enforcement Act, the act was voted in by
California voters through the initiative process. The
state establishes two lists, one of which contains
compounds known to the state to cause cancer, while
the other list contains compounds known to be
fetotoxic. Labeling requirements were established to
assure that anyone potentially exposed to compounds
on the list is notified. Since an advisory committee
periodically reviews the lists and adds compounds, the
list is always changing.
The Resource Conservation Recovery
Act of 1976 (RCRA):
Administered by the EPA, the act regulates the
activities of generators, transporters and those who
treat, store or dispose of hazardous wastes, and
provides “cradle to grave” authority to control
hazardous wastes from their generation to their
ultimate disposal. RCRA regulations establish criteria
to identify which wastes are hazardous and in what
quantities, concentrations, forms of disposal,
monitoring hazardous waste sites and regulating
underground storage tanks.
Reasonability Available Control
Technology (RACT):
Technology required to be installed on existing major
sources in attainment areas. RACT reflects controls
EPA has identified in CTG’s or other guidance.
Right-To-Know:
OSHA enacted the Hazard Communication Standard
in 1985 to mandate occupational hazard
communications to employees. Both state and local
laws pertaining to this subject are preempted by federal
standard, unless a federally approved state plan is in
effect.

SARA Title lll:
The main requirements for Title lll (the Emergency
Planning and Community Right-To-Know Act) of the
Superfund Amendments and Reauthorization Act
(SARA) involve sections governing Extremely
Hazardous Substances, CERCLA hazardous
substances, the Toxic Release Inventory and MSDS
categories.
*SARA Section 302 - Threshold planning quantity of
Extremely Hazardous Substance for emergence
and notification.
*SARA Section 304 - This section lists the CERCLA
hazardous substance subject to emergency release
notification.
*SARA Section 311/312 - Delineates health and
physical hazard categories for MSDS Reporting.
*SARA Section 313 - The Toxics Release Inventory
(TRI). Facilities that handle chemicals designated in
the TRI must complete a toxic chemical release
form annually detailing releases during the
preceding calendar year. These releases may be
allowed under air or water permits, may be spills of
waste or product
materials or may be fugitive emissions. The
reporting threshold for 1989 and thereafter is 25,000
pounds. A de minimis limit applies to toxic
chemicals present in concentrations below 1%, or
0.1% if the chemical is a
carcinogen. The TRI is placed in a database open
to the public. Environmental groups use TRI
information to put pressure on industrial firms to
reduce their emissions.
South Coast Air Quality Management
District (SCAQMD):
The air pollution control body established in Southern
California. SCAQMD governs air pollution control
efforts in Los Angeles County, Orange County,
Riverside County and San Bernardino County.
State Implementation Plans (SIP’s):
Plans that each state must develop to provide for
attainment and maintenance of the NAAQS’s.
Theshold Limit Value (TLV):
The American Conference of Governmental and
Industrial Hygienists reviewed several hundred existing
chemicals in order to provide industrial hygienists with
an evaluation of health hazards in the workplace. The
TLV is the limit believed by the ACGIH to which nearly
all workers may be repeatedly exposed day after day
without adverse affects. The airborne concentration is
expressed as TLV/TWA or TLV/STEL (Short Term
Exposure Limit).
