Syman LLC provides design services for all your environmental compliance needs.

Stormwater Pollution Prevention Plans (SWPPP) and Erosion and Sediment Control Plans (ESCP)

We have experience preparing these documents for projects throughout Idaho, the local municipalities and some of the surrounding States. We have a library of stormwater pollution prevention regulations, BMP details and specifications. Our personnel have a depth of experience and keep up with current regulations so you don’t have to.

Dewatering Plans

We can help you develop a dewatering plan for your project. We have experience in calculating settling pond sizes and can tailor any plan to the specific equipment you intend to use.

Site Specific Details and Calculations

We can provide documentation of the effectiveness of most BMPs, soil loss calculations, erosivity calculations and much more for your project. When required, we draft custom BMP details, specification and provide site specific operations and maintenance procedures for your site or specific BMPs.

Permanent BMPs Design

Syman can design permanent structural BMPs such as rip rap, retaining structures, reinforced slopes, retention and infiltration basins.

Spill Prevention

We provide Spill Prevention Control and Countermeasures Plans (SPCCP) for oil storage on construction, industrial and agricultural sites. Syman can also design permanent or temporary secondary containment systems at your site.


Syman Provides projects with inspection services required by Construction or Industrial Federal Stormwater Permits. Syman inspectors perform inspections to the standards found in the EPAs General Permits. We maintain records including photographs and update SWPPP documents on site. We can perform regularly scheduled inspection or perform audits on site as requested. We can also monitor turbidity and other pollutants on site.

Multi-Sector General Permits

Syman provides SWPP design for industrial facilities required to have coverage under the Multi-Sector General Permit (MSGP) for stormwater discharges. Syman can also provide inspection and monitoring of these facilities.


Syman provides training for compliance with construction and industrial stormwater compliance. Training can be customized to the needs of your project or facility. Training can be on-site in conjunction with inspection services or classroom training. Syman has personnel experienced in training and several pre-prepared handouts and presentations ready to suit your needs.
