Environmental Management Systems

We have established, documented, implemented, and maintained an EMS, based on ISO 14001 principles, since 2011. Through the process of internal and external audits/inspections, and a robust Corrective Action Program, we work to continually improve its effectiveness. APS’s Environmental Stewardship and Sustainability Policy establishes our vision and standards for environmental stewardship, performance and compliance. These standards ensure our company’s environmental programs and activities support our corporate environmental policy, goals and company vision to provide a sustainable energy future.

In addition to strengthening our environmental awareness, lowering environmental risks and ensuring a high level of environmental compliance, the policy is fully integrated with all laws, regulations and other applicable requirements concerning the environment at all APS facilities and construction projects.

All APS employees, visitors, contractors, sub-contractors and independent contractors performing services are required to comply with the company’s EMS.

Implementing an EMS helps us achieve improved performance in several ways, including:

  • Identify and control the environmental impact of our activities, products and services 
  • Standardize our operational approach to managing environmental issues at our facilities through fulfilment of our compliance obligations
  • Improve our environmental performance and reduce environmental risks 
  • Employ a systematic approach to setting environmental objectives and targets, achieving these targets and demonstrating that they have been achieved

Voluntary Environmental Stewardship Program

As a result of having an effective EMS in place, four of our power plants have received the Platinum Level Voluntary Environmental Stewardship Program (VESP) with Superior Compliance History designation from the Arizona Department of Environmental Quality (ADEQ). This is the highest award given under this program. Per ADEQ, this three-year recognition is given to a facility that has met the Gold Level standard, has a functioning EMS with at least one completed audited EMS cycle, and commits to community outreach. We look forward to adding our other sites to this list as we continue our commitment to operational excellence and environmental stewardship.
