GRI offers the following services:UST Installation Engineering – Our licensed Professional Engineer employs appropriate engineering practices when designing underground storage tank systems. Plans for new or replacement UST systems ensure that work performed on UST systems meets regulatory and compatibility requirements.Storm Water Pollution Prevention Plans (SWPPP) and Permits – a site-specific document or collection of documents that identifies the potential sources of storm water pollution, describes storm water control measures, such as best management practices, to reduce or eliminate the identified pollutants, and that also identifies procedures operators will implement to comply with specific permit conditions. A SWPPP can be provided for a number of circumstances, but the most common is to address storm water pollutants during construction activities and during operation of industrial activities. It serves as a guidebook of practices that you will use at your location or project to make sure that the storm water discharged off your location is as clean and unpolluted as possible. Vapor Barrier Dispersion Design – Develop a plan that concentrates on preventing volatile contaminant vapors from entering buildings where their accumulation could result in inhalation or explosive hazards. GRI’s experienced Professional Engineer can design a plan that includes vapor barriers to prevent vapor intrusion into buildings.Sedimentation and Erosion Control Plans – Problems associated with construction activities, like soil erosion, water pollution, flooding, stream channel damage, decreased ground water storage, slope failures, and damage to adjacent or downstream properties can be successfully minimized by implementing erosion and sediment control measures on construction sites. These measures help prevent soil movement or loss, enhance project aesthetics and eliminate appreciable damage to off-site receiving channels, property and natural resources. GRI can develop a plan that contains all the required elements to establish clearly which control measures are intended to prevent erosion and offsite sedimentation. The plan will serve as a blueprint for the location, installation, and maintenance of practices to control all anticipated erosion and prevent sediment from leaving the site. The approved erosion and sedimentation control plan—showing the location, design, and construction schedule for all erosion and sedimentation control practices—should be a part of the general construction contract.
