Environmental Impact Reporting

All of ISE’s technical services are available in a variety of environmental formats to satisfy local, state, and federal reporting requirements. ISE has prepared over the years, every manner of environmental documentation including CEQA and NEPA technical assessments, environmental initial studies (IS), mitigated negative declarations (MND), federal no significant impact statements (FONSI), and Environmental Impact Reports (EIR’s) / Environmental Impact Statements (EIS’s).

ISE has also co-authored numerous environmental documents with larger A&E firms, providing necessary technical subject matter and focused environmental sections as part of a larger document.

Featured Video Clip (Shock Wave)

A video taken by ISE showing the supersonic expansion of high pressure natural gas in a pipeline. 

The shock wave is clearly visible at the 1:00 min mark as a white cloud above the end of the pipe and produces an acoustic overpressure of close to 140 dB - which is as loud as a rocket engine.
