Environmental Impact and NEPA

MACTEC regulatory compliance experts explore, develop and deliver convincing technical arguments to offer alternative measures that frequently save clients significant costs. Rather than passively accepting conservative interpretations of environmental regulations—such as the National Environmental Policy Act of 1969 (NEPA)—that can cost your company excessive funds, it’s prudent to consult MACTEC to serve as an advocate to look after your best interests.

MACTEC is adept in all phases of the NEPA process:

• Environmental Assessment (EA) and Environmental Impact Statement (EIS)
• Project scope and definition (Purpose and Need)
• Development and evaluation of Action Alternatives
• Accurate mapping and documentation using global positioning systems (GPS) and geographic information system (GIS) tools
• Thorough and concise impact analysis
• Analysis of cumulative and secondary impacts
• Identification and evaluation of permitting and mitigation requirements
• Development of mitigation design, management plans and effectiveness monitoring
• Preparation of all required administrative notices, findings and records of decision
