Our services include engineered designs for BMPs such as diversion channels, ditches, dikes, berms, check dams, slope drains, sediment ponds, and snow management. Additionally, we prepare calculations for wind and stormwater erosion.
Plan preparation includes guidance for maintaining compliance with EPA’s Construction General Permit (CGP) and the Multi-Sector General Permits (MSGP).
ABCO Engineering provides sector specific consulting for inspection and monitoring at industrial sites. Specific tasks include water monitoring, facility inspections and assistance with reporting results to the EPA.
Stormwater Pollution Prevention Plans (SWPPP)
Our experience with EPA’s Construction General Permit (CGP) and the Multi-Sector General Permits (MSGP) are unparalleled. We go beyond meeting the minimum requirements in the permit by providing engineered designs for BMPs such as sediment ponds, erosivity, and stormwater retention. For industrial facilities, in addition to preparing SWPPPs we provide monitoring, including water sampling, testing and assistance with reporting results to the EPA through the online monitoring tools. If required we can design BMPs to treat stormwater if discharges are not meeting benchmark requirements, or re-design stormwater runoff plans to eliminate or reduce runoff and minimize permit conditions.
Spill Prevention Control and Countermeasure Plans
We prepare Spill Prevention Control and Countermeasure Plans (SPCCP) for farms, oil distributors, manufacturing and mining facilities. Preparation of the SPCCP plan includes design of secondary containment in compliance with 40 CFR part 112 regulations as well as recommendations for passive containment.
ABCO Engineering has completed designs of concrete and geomembrane containment systems as well as covered storage areas and loading racks for permanent and temporary installations.
We hold NRCS Technical Service Provider (TSP) registration for assisting with Agricultural facilities.
In addition to MSGP SWPPPs and the Spill prevention work we prepare reclamation plans required for surface mining facilities. Our reclamation plans meet the Idaho Department of Lands criteria. We are familiar with dryland and wetland re-vegetation plans, soil preparation and seeding techniques.
ABCO Engineering prepares engineered designs for streambank protection using mechanically anchored revetments, rip-rap, vegetative stabilization and combinations of these. We have successfully combined our experience with stormwater pollution prevention, and other state agency permits for working in waterways. Our knowledge of retaining structures and slope stability have helped us to successfully engineer streambank restoration and stabilization projects.
We complete drawings applications, calculations and meet with the Army Corps when required to obtain permits (404 or dredge and fill permits) for working in waterways. Our past experience includes permits for temporary construction in waterways such as stream crossings, placement of cofferdams, temporary supports, bypass pumping. We have also prepared permits for placement of rip rap, shoreline repair, re-vegetation and streambank stabilization.
