background

Honeywell Aerospace operates a 54-acre manufacturing facility with outdoor industrial activity including hazardous waste and chemical storage areas, equipment and salvage lots, scrap metal storage areas, air exhaust stacks, cooling towers, and a waste water treatment system. To achieve compliance with their NPDES permit requirements, Honeywell Corporate selected Pacific Stormwater to provide multiphase on-call stormwater services.

challenge

Originally constructed in 1961, the Facility has minimal greenspace, aging infrastructure, deteriorating hardscape, and extensive outdoor industrial activity. With proximity to a major expressway (I-405) and subject to substantial upgradient offsite discharge, the Site struggled to identify sources to control the elevated metals observed in stormwater. 

solution

Pacific Stormwater provided an initial sitewide infrastructure inventory, including a GPS location survey for 93 catch basins, 6 trench drains, and 113 roof drains, and associated conveyance piping followed by a drainage basin review which delineated 11 sub-basins at the site resulting in 5 substantially different compliance points. Pacific Stormwater conducted a source control evaluation and subsequently developed and designed site improvements to mitigate the findings.
