Sims streamlines stormwater management

Metals recycling leader reduces the costs and complexity of stormwater permitting, winning praise from regulators in the process


In order to comply with the California Industrial General Permit (IGP), Sims Metal Management needed to complete site maps and stormwater pollution prevention plans (SWPPPs) for seven northern California locations. These steps normally cost in excess of $30,000 per year and updates cost approximately $1,000+ per location with multiple updates per year based on changing industrial activities. Sims also needed to know when storms were forecast to alert staff about the steps they needed to take to comply with the IGP. They need these capabilities in order to avoid fines or the threat of lawsuits.


Instead of spending extensive amounts of time and money on completing required site maps, Sims is now using the Mapistry platform and mobile  app to digitally capture facility locations and mark-up required data points within a matter of hours, not days.

Over the past two years, Sims has also used the Mapistry platform to log inspection data, make real-time updates to site maps, and to centrally manage and track all of their compliance activities and reporting without having to worry about missing a deadline or becoming non-compliant. Upgrading to digital compliance processes and recordkeeping has drastically reduced the amount of time and effort required to manage stormwater permitting across several locations, which has ultimately freed up more staff time to focus on achieving other business goals. Additionally, they have minimized the costly risks and delays that arise from manual and paper-based reporting.

Mapistry has provided more than just software for Sims, they also evaluated their current stormwater system and industrial activities to help them design a new treatment system in order to keep them in-compliance with state mandated Numeric Action Levels (NALs). The treatment system utilizes existing stormwater infrastructure and retention capacity to reduce costs and increase treatment effectiveness. Additionally, Mapistry trained Sims’ staff to be a Qualified Industrial Stormwater Practitioner (QISP) and assisted with the Level 1 Exceedance Response Action (ERA) process under the California Industrial General Permit (IGP).

Sims Metal Management is the world’s largest listed metals and electronics recycler. The company has over 250 locations on five continents, and more than 6,000 employees.

They use Mapistry to:

  • Manage stormwater on seven sites in northern California
  • Draft and edit stormwater facility maps and SWPPPs
  • Create maps for safety, spill plans, electrical lines, and material storage plans
  • Track upcoming storms and log rainfall amounts
  • Comply with stormwater regulations and avoid fines and lawsuits
