General Project Information
The Risk and Technology Review (RTR) is a combined effort to evaluate both risk and technology as required by the Clean Air Act (CAA) after the application of maximum achievable control technology (MACT) standards. Section 112(f) of the CAA requires EPA to complete a Report to Congress that includes a discussion of methods the EPA would use to evaluate the risks remaining after the application of MACT standards. These are known as residual risks. EPA published the Residual Risk Report to Congress in March 1999. Section 112(f)(2) directs EPA to conduct risk assessments on each source category subject to MACT standards, and to determine if additional standards are needed to reduce residual risks. Section 112(d)(6) of the CAA requires EPA to review and revise the MACT standards, as necessary, taking into account developments in practices, processes and control technologies. The methodology for conducting these reviews is described in: Risk and Technology Review (RTR) Risk Assessment Methodologies: For Review by the EPA’s Science Advisory Board with Case Studies – MACT I Petroleum Refining Sources and Portland Cement Manufacturing (EPA-452/R-09-006). The Science Advisory Board (SAB) RTR Methods Review Panel held a meeting on July 28-29, 2009 to review this document, and a final report of their review is available at the SAB website .
The EPA is under a consent decree that establishes deadlines for completing the proposed and final actions for the source categories. The deadlines for the proposed and final rules for these source categories are shown in the following table.

The state of TX provided a crosswalk to match the state EPN (Emission Point Number) IDs and the federal NEI IDs. The EPN IDs were submitted by TX facilities and the NEI IDs were submitted by the state of TX to EPA. The three zipped Excel files below contain the crosswalk data. They provide separate files for: Anderson - Hardin Counties, Harris County, and Harrison - Zavala Counties.

Section 112(f(2)
(2) EMISSION STANDARDS.--
(A) If Congress does not act on any recommendation submit-
ted under paragraph (1), the Administrator shall, within 8
years after promulgation of standards for each category or
subcate-gory of sources pursuant to subsection (d), promul-
gate stand-ards for such category or subcategory if
promulgation of such standards is required in order to
provide an ample margin of safety to protect public health
in accordance with this sec-tion (as in effect before the
date of enactment of the Clean Air Act Amendments of 1990)
or to prevent, taking into consid-eration costs, energy,
safety, and other relevant factors, an adverse environmental
effect. Emission standards promulgated under this subsection
shall provide an ample margin of safety to protect public
health in accordance
with this section (as in effect before the date of enactment
of the Clean Air Act Amendments of 1990), unless the
Administrator determines that a more stringent standard is
necessary to prevent, taking into consideration costs,
energy, safety, and other relevant factors, an adverse
environmental effect. If standards promulgated pursuant to
subsection (d) and applicable to a category or subcategory
of sources emitting a pollutant (or pollutants) classified
as a known, probable or possible human carcinogen do not
reduce lifetime excess cancer risks to the individual most
exposed to emissions from a source in the category or
subcategory to less than one in one million, the
Administrator shall promulgate standards under this
subsection for such source category.
(B) Nothing in subparagraph (A) or in any other provision
of this section shall be construed as affecting, or applying
to the Administrator's interpretation of this section, as in
effect before the date of enactment of the Clean Air Act
Amendments of 1990 and set forth in the Federal Register of
September 14, 1989 (54 Federal Register 38044).
(C) The Administrator shall determine whether or not to
promulgate such standards and, if the Administrator decides
to promulgate such standards, shall promulgate the standards
8 years after promulgation of the standards under subsection
(d) for each source category or subcategory concerned. In
the case of categories or subcategories for which standards
under subsection (d) are required to be promulgated within 2
years after the date of enactment of the Clean Air Act
Amendments of 1990, the Administrator shall have 9 years
after promulgation of the standards under subsection (d) to
make the determination under the preceding sentence and, if
required, to promulgate the standards under this paragraph....
112(d)(6)
(6) Review and revision.- The Administrator shall review, and
revise as necessary (taking into account developments in practic-
es, processes, and control technologies), emission standards
promulgated under this section no less often than every 8 years.
