Environmental Compliance and Permitting Services

Navigating the permitting process can be complex, especially for projects with tight timelines or unique environmental considerations. At NTH, we partner with clients to develop tailored permitting strategies that align with project goals and schedules. By assessing regulatory requirements at the local, state, and federal levels, we identify potential challenges early and create proactive solutions to minimize delays. Our team’s understanding of environmental laws and agency protocols allows us to streamline approvals and coordinate effectively with regulators. Whether it’s a new facility, infrastructure upgrade, or redevelopment project, we design strategies that keep your project moving forward.

Staying compliant in a rapidly evolving regulatory landscape requires vigilance and expertise. NTH provides comprehensive regulatory compliance audits to help clients assess their current operations and identify potential risks. Our audits examine air and water discharges, waste management practices, hazardous materials handling, and more to ensure alignment with applicable environmental regulations. Beyond identifying gaps, we deliver actionable recommendations and support the implementation of corrective measures. With our audits, clients gain peace of mind knowing they are meeting regulatory obligations while reducing the risk of costly violations and penalties.

Air and water quality regulations are critical components of environmental compliance for industrial, municipal, and energy projects. NTH’s experts help clients navigate these requirements by preparing permit applications, supporting modeling and monitoring efforts, and facilitating agency interactions. Our team has extensive experience securing air permits for emissions sources and water discharge permits (including NPDES) that meet both operational needs and environmental protection standards. We focus on developing solutions that balance compliance with efficiency, helping clients maintain sustainable operations while meeting regulatory expectations.

Construction activities can have significant impacts on stormwater quality, making compliance with stormwater regulations essential. NTH develops and implements Stormwater Pollution Prevention Plans (SWPPP) that meet federal, state, and local requirements. Our services include site evaluations, best management practice (BMP) design, permit applications, and ongoing compliance monitoring. By integrating effective erosion and sediment control measures, we help clients protect surrounding ecosystems, avoid costly violations, and maintain project timelines during all phases of construction.

Large-scale projects often require a detailed understanding of their potential environmental impacts. NTH provides Environmental Impact Assessments (EIA) that meet the requirements of NEPA, SEPA, and other local or regional environmental review processes. Our multidisciplinary team conducts thorough analyses of air, water, soil, and ecological systems to evaluate potential impacts and develop mitigation measures. With extensive experience in stakeholder engagement and agency coordination, we help clients navigate environmental reviews efficiently, paving the way for project approvals and successful implementation.
