State report questions Louisiana’s air quality enforcement Though Louisiana’s air quality has improved in recent years, state regulators should be doing more to ensure companies are complying with air quality rules, the Louisiana Legislative Auditor says. The Louisiana Department of Environmental Quality agreed with some of the LLA’s conclusions but said adding staff as the auditor’s office suggests may not be affordable. According to the LLA’s analysis of U.S. Environmental Protection Agency data, the number of “good” air quality days in Louisiana has increased from 191.9 days in calendar year 2008 to 232 days in 2018, or about a 21 percent improvement. Meanwhile, the number of unhealthy days for sensitive groups decreased about 75 percent, from 14.3 days to 3.6 days.
