A client identified a high-risk pipeline exposure within a primary channel. Non-native species growth within the channel altered low-flow dynamics within the active floodplain, forcing unusually high flows and causing long-term and on-going risk to the pipelines. Tegre staff designed a bank reinforcement at the site of the pipe exposure, re-establishing a stable bank, and developing a channel augmentation designed to promote near pre-existing low-flow channel dynamics for long term protection. Tegre staff joined archaeological consultants to prepare necessary environmental products to satisfy tribal regulation and to obtain United States Army Corps of Engineers project authorization under §404 of the CWA and obtain water quality certification through the Environmental Protection Agency under §401 of that Act. Tegre staff also provided on-site Environmental Inspection services during project execution to ensure compliance with all involved agency mitigations.
Tegre has/is supporting clients with stormwater management plans. Scope of services includes one site review to refine locations for chosen BMPs, narrative for stormwater management plans that meet state and federal standards, BMP implementation maps (legend and materials sheet, during-construction phase sheet, and interim reclamation sheet), BMP installation detail sheets, inspection and monitoring for completion per jurisdictional requirements.
Tegre performed Phase I ESA including site inspection, records review and interviews, and a final report documenting methods and findings. Completion of the ESA provided for examination of recognized environmental conditions associated with the properties, including an evaluation of the former uses, existing conditions, and potential for contaminants to migrate.
Tegre supported a client in a new development and was responsible for permitting efforts for a multi well pad development program. Tegre’s scope of work included site selection support, survey, regulatory support, environmental clearance, APD packages and exhibits, plats, alignment sheets, and site plans.
Project consisted of providing client with a reclamation plan for field wide abandonment of wells, gathering lines, pads and access roads. Scope included as-built survey and mapping of existing facilities and above and below ground pipelines, preparation of site exhibits, field prescriptions, civil engineering/design, on-sites with local jurisdiction, final reclamation plan, and support with implementing plan.
