Petroleum Storage Tank Site Management

Souder, Miller & Associates provides petroleum storage tank (PST) site management services for owners, operators, developers, municipalities, utilities, industrial clients, and public agencies across Arizona, New Mexico, Texas, Colorado, and Wyoming. Our environmental professionals support projects involving aboveground storage tanks, underground storage tanks, former tank systems, petroleum releases, abandoned infrastructure, and sites with uncertain historical use.

From initial site evaluation through regulatory closure, SMA helps clients manage petroleum storage tank projects with a practical focus on compliance, cost control, risk reduction, and long-term site use. Our services include investigation, remediation, monitoring, reporting, and coordination with applicable state and local regulatory agencies.

Full-Service PST Investigation, Remediation, and Monitoring

Petroleum storage tank sites can present complex environmental and redevelopment challenges. Releases from tanks, dispensers, piping, sumps, and historical fuel-handling areas may affect soil, groundwater, surface water, utilities, structures, or vapor pathways. SMA helps clients identify these conditions, define the extent of impacts, and develop appropriate corrective actions.

Our PST site management services include:

  • Site inspections and historical records review
  • Tank system evaluation and release response support
  • Soil, groundwater, soil vapor, and surface water sampling
  • Assessment of petroleum hydrocarbons, volatile organic compounds (VOCs), fuel additives, metals, and related constituents
  • Monitoring well planning, installation oversight, sampling, and reporting
  • Development of investigation work plans and corrective action plans
  • Remediation system evaluation, design, implementation support, and performance monitoring
  • Excavation planning, confirmation sampling, and disposal coordination
  • Vapor intrusion screening and mitigation support
  • Regulatory reporting and agency coordination
  • Closure documentation and long-term monitoring support

SMA works with clients to select investigation and remediation approaches that are appropriate for the site conditions, regulatory framework, project schedule, and intended property use. Whether the project involves an active fueling facility, a former service station, a municipal maintenance yard, an industrial site, or a property being evaluated for redevelopment, SMA provides technically sound support from initial evaluation through completion.

Remediation System Design, Construction, and Operation

SMA provides remediation system design, construction oversight, startup support, and operation and maintenance services for petroleum-impacted sites. Our remediation work is overseen by registered professional engineers and supported by environmental professionals with decades of experience evaluating, designing, implementing, and optimizing corrective action approaches for soil, groundwater, and vapor impacts.

Petroleum remediation requires solutions that are technically sound, constructible, cost-effective, and appropriate for the regulatory pathway and future use of the site. SMA evaluates site-specific conditions such as geology, groundwater depth and gradient, contaminant distribution, vapor migration potential, utility conflicts, access limitations, and treatment objectives to develop practical remediation strategies.

Typical remediation technologies utilized by SMA include:

  • Soil vapor extraction systems for volatile petroleum impacts in vadose-zone soils
  • Air sparging systems to enhance volatilization and treatment of dissolved-phase petroleum constituents
  • Excavation, segregation, confirmation sampling, and disposal coordination for impacted soil
  • Thermal desorption evaluation and implementation support where appropriate for petroleum-impacted media
  • Groundwater pump-and-treat systems for hydraulic control, plume management, or contaminant mass removal
  • Addition of oxygenated fluids or other amendments to enhance aerobic biodegradation of petroleum constituents
  • Combined remedy approaches where multiple technologies are needed to address complex site conditions

SMA can support remediation projects from conceptual design through final closure, including feasibility evaluation, pilot testing, design drawings and specifications, contractor coordination, construction observation, system startup, performance monitoring, optimization, reporting, and regulatory communication. Our team focuses on designing remedies that are reliable, maintainable, and aligned with client goals, whether the project requires aggressive source-area treatment, long-term plume management, redevelopment support, or a pathway to regulatory closure.

Regulatory Compliance Across the Mountain West and Southwest

Petroleum storage tank requirements vary by state, local jurisdiction, tank type, release status, and site history. SMA supports PST projects in Arizona, New Mexico, Texas, Colorado, and Wyoming, helping clients navigate applicable investigation, corrective action, monitoring, and reporting requirements.

Our team prepares clear, defensible documentation for regulatory review, including:

  • Site characterization reports
  • Monitoring reports
  • Corrective action plans
  • Remediation summaries
  • Closure requests

We understand that successful PST management requires both sound technical work and effective communication with agencies, property owners, contractors, and project stakeholders.

Subsurface Utility Engineering for Tank and Line Evaluations

SMA’s subsurface utility engineering (SUE) services can play an important role in petroleum storage tank site evaluations. Unknown or abandoned tanks, fuel lines, vent lines, product piping, electrical conduits, and related infrastructure can create environmental risk, construction conflicts, and redevelopment delays.

Using SUE and utility location methods, SMA can help identify:

  • Unknown or abandoned tanks
  • Fuel lines
  • Vent lines
  • Product piping
  • Electrical conduits
  • Other buried infrastructure not shown on plans or historical records

This support can be especially valuable during due diligence, pre-demolition planning, site redevelopment, excavation, and environmental investigations where abandoned tanks or piping may still be present.

By integrating environmental investigation with utility location capabilities, SMA helps clients better understand subsurface conditions before excavation, drilling, or construction begins.

Drilling and Field Support Through IME

SMA’s relationship with Inberg-Miller Engineers, another Azurite-owned company, provides access to substantial core and hollow-stem auger drilling resources. This capability strengthens our ability to support petroleum storage tank investigations that require soil borings, monitoring wells, geotechnical information, or subsurface characterization in challenging site conditions.

Access to these drilling resources helps SMA:

  • Coordinate field activities efficiently
  • Maintain flexibility during investigation and remediation projects
  • Support clients with a broader range of environmental and site development needs

Integrated Environmental and Site Development Support

Petroleum storage tank issues often arise in the context of property transactions, facility upgrades, utility work, demolition, construction, or redevelopment. SMA’s environmental services can be coordinated with our engineering, geomatics, SUE, and site development teams to help clients manage the full project picture.

This integrated approach allows SMA to support petroleum storage tank projects while also considering:

  • Grading
  • Drainage
  • Utilities
  • Access
  • Permitting
  • Construction sequencing
  • Property constraints
  • Future development objectives

The result is practical technical guidance that supports both regulatory compliance and the client’s broader project goals.

Practical Solutions for Petroleum-Impacted Sites

SMA understands that every PST site is different. Some projects require rapid response and focused investigation. Others involve long-term monitoring, complex groundwater conditions, redevelopment constraints, or coordination with multiple stakeholders. Our goal is to help clients make informed decisions based on reliable data, regulatory requirements, and the practical realities of each site.
