Revisions to Chapter 7 published August 29, 2017 (82 FR 40949) LAd58 did not change the SIP-approved Chapter 7 but was intended to correct errors in the Chapter 7 CFR amendatory language. The August 29, 2017 Federal Register Chapter 7 amendatory language did contain errors which are corrected in the Chapter 7 table in the "Current Louisiana SIP-Approved Regulations" document that this document is linked to in this web site.

A. General. It is hereby declared to be the public policy of the state to achieve and maintain such levels of air quality as will protect human health and safety, and to the greatest degree practicable prevent injury to plant and animal life and property, foster the comfort and convenience of the people, promote the economic and social development of this state and facilitate the enjoyment of the natural attractions of the state.

Regulations.gov docket EPA-R06-OAR-2012-0434 [LA039].
B. Particulate Matter. The purpose of this Chapter is to
maintain concentrations of particulate matter in the ambient
air at levels which will not cause damage or injury to plant
or animal life. In addition to health considerations,
attainment of the standards will result in economic and
aesthetic benefits such as increased visibility and reduced
soiling and corrosion.

E. Reserved.
F. Atmospheric Oxidants. It is the purpose of this Subsection to establish ambient air quality standards for the state for atmospheric oxidants and to enumerate methods for measuring oxidant concentrations in the ambient air.

Section 705. Standards
Approved by EPA 03/08/89 (54 FR 09795) at 52.970(c)(49) effective 05/08/89.
The standards of ambient air quality listed in Tables 1 and 1a define the limits of air contamination by particulates and gases, above which limits the ambient air is hereby declared to be unacceptable and requires air pollution control measures. Until additional pertinent information becomes available through surveillance and research with respect to the effects of the air contaminants listed in Tables 1 and 1a, the air quality limits listed in Tables 1 and 1a shall apply in Louisiana. The limits stated include normal background levels of particulates and gases.
AUTHORITY NOTE: Promulgated in accordance with R.S. 30:1084.

Section 707. Degradation of Ambient Air Having Higher Quality than Set Forth in these Sections Restricted
Approved by EPA 03/08/89 (54 FR 09795) at 52.970(c)(49) effective 05/08/89.
As of the effective date of these regulations all processes which currently result in higher ambient air quality than shown in Tables 1 and 1a shall be maintained at the higher process quality level or better unless it can be affirmatively demonstrated to the administrative authority that a change in quality is justifiable.
