Enterprise Environmental Factors updated where? and why?

EEFs are typically updated within your PMIS or organizational process assets whenever market conditions, legal requirements, or physical infrastructure change. The why is simple, outdated EEFs lead to poor risk assessments and flawed decisions.

For practical environmental data that often feeds into EEFs, especially around stormwater compliance, I'd point you to https://uswac.org/. It's a solid, real-world reference I've found genuinely useful for understanding regulatory and environmental factors that frequently trigger EEF updates. Definitely worth a quick visit.
