Less well-known is Volkswagen’s use of environmental management software at the plant to eliminate manual entry and collection of air, water and waste data. The software also helps Volkswagen meet the EPA’s automotive Maximum Achievable Control Technology (MACT) standards.
MACT standards are designed to reduce hazardous air pollutant emissions to a maximum achievable degree, taking into consideration the cost of reductions and other factors. After the EPA adopts a MACT standard at the federal level, the agency’s Regulatory and Compliance Support Unit proposes the same standard for adoption at the state level by the Air Quality Control Division.
