PERMITTING REFORM RECOMMENDATIONS CLICK TO EDIT MASTER TITLE STYLE STREAMLINE PERMITTING ESTABLISHING PURPOSE & NEED • Unnecessary delays from changeover in • Population and demand projections people, policies, concepts and procedures – developed/approved by state should be process should only take 2-3 years sufficient STATUTE OF LIMITATIONS TO PERMIT USE OF BEST AVAILABLE CHALLENGES INFORMATION • Should be shortened to 180 days vs. 5+ years • Applicants shouldn’t be required to to avoid further delays of litigation develop new or updated information late in permitting process – recommend statutory deadline. FEDERAL FUNDING FOR SUPPLY PROJECTS • Applicant and agencies should have binding agreement on impact assessment • Water supply lowest priority and lowest funded methods required for evaluation. program of USACE – need Congress to approve more funding and resources COMPENSATORY MITIGATION • Environmental benefits of supply projects should be considered as offsets to impacts
