On November 12, 2008 the EPA substantially strengthened the National Ambient Air Quality Standards (NAAQS) for Lead (see 73 FR 66964 (PDF). The EPA mandated a tenfold reduction in the level of the primary (health-based) standard from 1.5 micrograms per cubic meter to 0.15 micrograms per cubic meter, measured as total suspended particles (TSP). Additionally, the secondary (welfare-based) was also revised to be identical in all respects to the primary standard.
In conjunction with strengthening the Lead NAAQS, the EPA also promulgated new monitoring requirements.
Conecsus is being monitored by the Texas Commission on Environmental Quality (TCEQ) for the EPA and through implementation of multiple operational and engineering controls has achieved and surpassed the new National Ambient Air Quality Standard for every rolling three-month monitoring period since the monitor was installed on-site in January 2011.
This commitment to the public safety, employee safety, and environmental stewardship is the hallmark that Conecsus vows to operate by. Early compliance with these standards has set Conecsus apart from its competitors and allowed us to achieve the ISO 14001 Environmental Management System certification, the highest certification achievable for the protection of the environment.
