15. Environmental Commitments What are the commitments? Question 1d: 15 Categorical Exclusion Training Class

16. Environmental Commitments Example Commitments: Commitment 1: Project will need Notice of Intent submitted to EPA Commitment 2: Project will need to comply with CGP or watershed specific CGP Commitment 3: Project will address local stormwater issues Commitments should be kept general at this point Only commit to what we know for sure 16 Categorical Exclusion Training Class
