Stormwater Pollution Prevention Plan Services

Stormwater runoff from construction, industrial, municipal, and commercial sites can carry sediment, chemicals, oils, debris, and other pollutants into nearby drainageways, arroyos, rivers, lakes, and groundwater recharge areas. Souder, Miller & Associates (SMA) helps public and private clients develop, implement, and maintain Stormwater Pollution Prevention Plans (SWPPPs or SP3s) that support regulatory compliance while fitting the practical needs of the site.

SMA provides stormwater compliance services throughout the Mountain West, including support for construction projects, industrial facilities, infrastructure improvements, transportation corridors, utility projects, energy sites, and municipal operations. Our multidisciplinary team understands the interaction between site grading, drainage, erosion control, construction sequencing, environmental permitting, and long-term facility management.

Stormwater Planning, Permitting, and Compliance

SMA assists clients with stormwater permitting and compliance under applicable federal, state, and local requirements, including National Pollutant Discharge Elimination System (NPDES) and state-delegated stormwater programs.

Our services may include:

  • Preparation of SWPPPs/SP3s
  • Permit applications
  • Notices of Intent (NOIs)
  • Notices of Termination (NOTs)
  • Inspection forms
  • Corrective action documentation
  • Supporting reports required by regulatory agencies or project owners

Each plan is developed to address the specific conditions of the project or facility, including site topography, drainage patterns, receiving waters, soil conditions, construction phasing, material storage areas, equipment staging, potential pollutant sources, and best management practices. SMA works with owners, contractors, operators, and agencies to produce clear, usable plans that can be implemented in the field.

Construction Stormwater Services

For construction projects, SMA supports stormwater compliance from early planning through project closeout.

Services can include:

  • Erosion and sediment control planning
  • Construction-phase SWPPP/SP3 preparation
  • Identification of temporary and permanent stormwater controls and best management practices (BMPs)
  • Permit coordination
  • Documentation for site stabilization and termination of permit coverage

SMA can help project teams address common construction stormwater concerns, including:

  • Disturbed soil management
  • Perimeter controls
  • Inlet protection
  • Stockpile management
  • Concrete washout
  • Vehicle tracking
  • Fueling and maintenance areas
  • Dewatering
  • Waste management
  • Final stabilization

Our goal is to help clients maintain compliance while reducing delays, field confusion, and the risk of enforcement actions.

Site Inspections and Compliance Monitoring

A stormwater plan is only effective if it is properly implemented and maintained. SMA provides site inspections and compliance monitoring services to evaluate whether required stormwater controls are installed, functioning, and maintained in accordance with applicable permit requirements and project specifications.

Inspection services may include:

  • Routine permit inspections
  • Storm-event inspections
  • Documentation of deficiencies
  • Corrective action recommendations
  • Photographic records
  • Inspection reports
  • Follow-up verification

SMA can also support contractor coordination, owner representation, and agency communication when stormwater compliance issues need to be addressed promptly.

Industrial and Facility Stormwater Support

SMA also assists industrial, municipal, commercial, and utility clients with facility stormwater compliance. These services may include evaluation of:

  • Outdoor operations
  • Material storage
  • Fueling areas
  • Loading areas
  • Waste handling
  • Vehicle and equipment maintenance areas
  • Drainage structures
  • Discharge points

Facility stormwater services can include:

  • Preparation or updating of industrial SWPPPs/SP3s
  • Monitoring plans
  • Sampling coordination
  • Benchmark and compliance reporting support
  • Employee training materials
  • Good housekeeping recommendations
  • Spill prevention coordination
  • Documentation needed for internal audits or regulatory review

Reporting, Documentation, and Regulatory Coordination

Stormwater compliance depends on accurate and timely documentation. SMA helps clients prepare and maintain required records, including:

  • Inspection logs
  • Corrective action records
  • Maintenance documentation
  • Discharge monitoring reports
  • Permit submittals
  • Certifications
  • Project closeout documentation

Our team can also assist with communication between owners, contractors, facility operators, municipalities, state agencies, and federal regulators. Whether the need is a single SWPPP/SP3 for a construction project or ongoing compliance support across multiple facilities or project sites, SMA provides practical, defensible, and well-documented stormwater services.

Integrated Engineering and Environmental Capabilities

SMA’s stormwater services are strengthened by our in-house engineering, environmental, geomatics, surveying, and construction support capabilities.

When needed, SMA can integrate stormwater planning with:

This integrated approach allows SMA to help clients move from permitting to implementation with fewer gaps between plan requirements and field conditions.

Serving the Mountain West

SMA provides stormwater pollution prevention planning, permitting, inspection, monitoring, and reporting services throughout the Mountain West. Our experience with arid and semi-arid environments, intense storm events, ephemeral drainageways, steep terrain, variable soils, and remote project locations allows us to develop stormwater compliance solutions that are appropriate for the region and practical for the people responsible for implementing them.

From construction projects and public infrastructure to industrial facilities and multi-site programs, SMA helps clients manage stormwater compliance with clear plans, responsive field support, and reliable documentation. For more information, contact SWPPP@soudermiller.com.
