3. UNDERGROUND STORAGE TANK MANAGEMENT

The U.S. Environmental Protection Agency estimates that 25% of all underground storage tanks (USTs) in the United States are currently leaking. Since most tanks are constructed of bare steel, they are extremely susceptible to corrosion. Any tank greater than 12-15 years of age-- beyond its useful life-- has a high potential for significant corrosion, followed by the leaking of its contents into the subsoil and groundwater.

Once a tank has leaked, the cleanup costs increase exponentially. According to financial data developed by one Midwestern state, the average tank removal cost is approximately $7,500.00. When the tank has leaked, the average cost jumps to over $86,000.00. Add to this issues such as lost revenues due to lengthy cleanups, fines from governmental agencies, lawsuits from adjacent property owners affected by the contamination, and loss of property value due to environmental concerns, and it is clear that avoiding leaking UST's is in every property owner's best interests.

AEROTECH’S MANAGEMENT STRATEGY FOR
UST REMOVAL OR ABANDONMENT IN-PLACE
THE "PHASED TASK RESPONSE"

To have a leaking underground storage tank is a major financial concern for any property owner. More often than not, facility owners are finding additional losses of time and money associated with UST removal simply because they rely on inexperienced or unorganized contractors to complete the job for them. Aerotech Environmental Consulting, Inc. has proven time and time again that with our experience and organized plan of attack, we can save a tank owner time and money. By using the Aerotech phased strategy detailed below, a tank owner is informed, organized and prepared to handle the UST removal effort in a way they will require the lowest investment of time and money. With our staff on the project, the owner will also the have peace of mind knowing that true professionals are on the job keeping the liabilities to a minimum as well.

TASK I: UST Investigation - In order to accurately assess the potential for subsoil contamination, soil borings may be conducted. The objective is to determine a to level of accuracy desired by the owner, the presence, severity, and extent of contamination.

TASK II: UST Removal and Abandonment Specification - In order to manage the contingent liability, legal responsibility, and potential exposure of the site owner regarding the handling, removal, disposal, and abandonment of the UST and contaminated media, a comprehensive specification is prepared for those specific concerns. Included within the specification is the scope of work, removal permits, and the operational project guidelines.

TASK III: Contractor Selection and Legal Submittals - The specification developed above will be used to both solicit bids from qualified contractors, and as the initial submittal to the applicable agency authority. Our project administrator will then review the bid information and conduct a cost analysis, then discuss our recommendations with the facility owner. Bids from contractors will include removal, cleaning and disposing of the UST, registration fees for the removal permit, removal of non-native fill around tank, backfilling of tank area with clean compacted fill, and restoration of the area to its pre-project condition.

TASK IV: Underground Storage Tank Removal - Once the contractor is selected, notice must given to the appropriate state agency to obtain the removal permit-- which can take thirty days. The removal effort will be managed by our tank specialists and engineers to ensure that the specifications are met, the work on site is professional, that all parties requiring notification are indeed notified, that the effort is scheduled to inconvenience the owner as little as possible, and to represent the owner's interests with the State regulators. When the tank is removed and the required soil remediated, soil samples of the excavation will be collected and analyzed by an state-accredited laboratory in order to satisfy applicable State requirements.

TASK V: Final Closure Project Documentation - Upon completion of the Site work, we will provide complete documentation of the project. This information will be forwarded to the applicable State agency, who will approve the final project submittal. For leaking USTs, a "clean closure" type document will be issued by the State. In most states, non-leaking tanks do not require final submittals. Unfortunately, many States require as much as three months review the documentation and provide the closure. However, our written documentation will satisfy most lenders, so that final transactions can be completed prior to the State's closure response.

The laws pertaining to USTs are difficult to interpret. Flexibility is built into UST regulations because no two tank sites are alike. This is why there are different courses of action for every situation. The Phased Task strategy is the most efficient and and effective concept for an owner to follow. The most important factors in dealing with UST's are time and money. Our plan allows for the lowest possible cost keeping in mind that time is of the essence.

4. VAPOR INSTRUSION, SCREENING AND ASSESSMENT

Migration of volatile chemicals from the subsurface into overlying buildings is called vapor intrusion (VI). Volatile organic chemicals in contaminated soils or groundwater can emit vapors, which may migrate through subsurface soils and may enter the indoor air of overlying buildings. Building depressurization may cause these vapors to enter the home through cracks in the foundation. Depressurization can be caused by a combination of wind effects and stack effects, which are the result of heating within the building and/or mechanical ventilation. In extreme cases, the vapors may accumulate in dwellings to levels that may pose near-term safety hazards, such as explosion. Typically, however, vapor concentrations are present at low levels, to which long-term exposure may pose increased risk for chronic health effects.

The term is not intended to include de minimis conditions that do not normally represent an unacceptable health risk to occupants and that generally would not be subject of an enforcement action if brought to the attention of appropriate governmental agencies. Such a condition is not a vapor intrusion condition. In order to determine the presence of Vapor Intrusion condition, good practice takes into consideration the ASTM (formerly the American Society of Testing and Materials) Standard Practice No. E2600-08, Assessment of Vapor Intrusion into Structures on Property Involved in Real Estate Transactions, approved by the ASTM Committee E50 on Environmental Assessment in March of 2008.

The ASTM Vapor Intrusion Standard Practice is a reasonably conservative screening process that relies upon information collected as part of the Phase I process, and gradually progresses towards a more complex and involved assessment involving the generation and use of Site specific data. If a Vapor Intrusion Condition ("VIC") is found to exist, the ASTM Practice describes the general mitigation alternatives. The VI Assessment is a four-tiered process: the first two tiers assess the potential for a VIC to exist, and if there is potential, the third tier is designed to provide confirmation that the VIC does in fact exist, or to reduce the level of uncertainty. The fourth tier provides general mitigation alternatives to address either a potential or existing VIC.

The Tier 1 Screening Process includes: (1) determination if there are any known or suspected contaminated sites in the Area of Concern; (2) for those known or suspected contaminated sites in the Area of Concern, determination of whether or not Chemicals of Concern may be present; and (3) if Chemicals of Concern in the Contaminated Plume may be present within the nearest edge of the subject Property . Generally, the Phase I Assessment relies upon the general ASTM VI Standard Practice for a Tier 1 Screen, modified by known Site and area-wide subsurface conditions; migration characteristics of Contaminants of Concern ; revision of the Appropriate Minimum Search Distance of Surrounding Properties and Up-Gradient Only Properties; and distance between Contaminated Plume and the subject Property.

1) If the linear distance from the nearest edge of a Contaminated Plume to the nearest structure on the subject Property - or to the subject Property boundary if there are no structures on the subject Property - is less than 100 feet, then the condition is considered to be a potential VIC. If the Chemicals of Concern are dissolved petroleum hydrocarbons, the distance must be less than 30 feet in order for a potential VIC to exist. (For additional information, refer to the ASTM E 2600-08, § 8.5.2.

2) As delineated in the ASTM VI Standard Practice, petroleum hydrocarbons are distinguished from other Chemicals of Concern because petroleum hydrocarbons often undergo significant bio-degradation in the vadose zone in the presence of oxygen - minimum five percent in the vadose zone soil gas.

5. INDOOR AIR QUALITY EVALUATIONS

The use of chemicals in everyday fabrics and materials has proliferated over the past 30 years, coinciding with closed HVAC systems allowing minimal outside air, which can often result in higher humidity within a building. In some cases, this combination results in chemical vapors and gasses, and the presence of biological agents such as bacteria and fungi being contained within and distributed throughout a building, causing discomfort and even illness to building occupants. This phenomenon is frequently referred to as the "Sick Building" Syndrome.

While indoor air quality is not specifically regulated, it is receiving more emphasis from EPA as witnesses in their publication, "Building Air Quality." The very real effects of the "Sick Building" Syndrome are disrupted business operations, low employee morale, diversions of management time and efforts, and real or threatened actions of law. The personnel of Aerotech Environmental Consulting, Inc. have been diagnosing "Sick Buildings" with its specialized staff of technicians and microbiologists.

AIRBORNE CONTAMINANTS AND PEL MONITORING

OSHA has established Permissible Exposure Limits ("PEL") for over 600 air contaminants, including such particulates and chemicals as welding fumes, wood dust, nuisance dusts, chlorine dioxide, solvents, ammonia, formaldehyde, and cleaning solvents. Industries affected by these PELs include dry cleaners, chemical and petrochemical plants, pulp and paper mills, and virtually every other process industry; hospitals, laboratories; fabricators, printers, and most other businesses which use chemicals.

MICRO BIOLOGICAL CONTAMINANTS

The presence of micro biological organisms and their byproducts is ubiquitous throughout the indoor and outdoor environments. Micro biological organisms can detrimentally effect buildings via the presence of their spores, off gassing, and airborne suspension of the organisms themselves. However, there is both no clear scientific evidence to support the conclusion that the mere presence of micro organisms is in itself a recognized environmental condition, or that any threshold level exists of airborne organisms of byproducts above which a negative impact to human health will likely result. Recognizing these factors, the Aerotech will conduct Site observations in an attempt to identify clearly known indicators of potential micro biological impact.

These indicators included: (i) obvious visual indications of micro biological organism growth is readily accessible areas; (ii) indicators of extensive or continued water intrusion or severe staining; (iii) secondary indicators such as smells and odors; and (iv) information obtained from the Key Site Manager and other knowledgeable personnel. Since the majority of micro biological growth tends to occur in enclosed, covered, and otherwise inaccessible building and interstitial spaces, the likelihood that micro organisms would not be observed even though present, is possible.

As such, even though no readily visible observations or indicators of micro biological impact were observed during the Site visit, a micro biologically-based problem could be present at the Site, even though not observed. If requested, Aerotech can perform minimally invasive inspections of interstitial building areas to more fully investigation the potential for microbial growth or impact.

6. LEAD MANAGEMENT SERVICES

In response to the heightened public awareness to the health risks of lead exposure, Congress enacted the Housing and Community Development Act of 1992, which directed OSHA to implement new lead standards for industry.

The OSHA Lead Exposure in Construction Standard as delineated in 29 CFR §1926.62 - effective October 3, 1993 - addresses activities, projects, handling, and disposal of materials in the presence of lead. The Standard requires both the facility owner and employer to either proactively determine the locations of potential exposure, or assume the existence of lead. While a variety of programs and responses can be triggered by various work activities, most facilities and employers will be required to institute a basic "Regulatory Response Initiative" generally consisting of:

  1. Facility Compliance Audit - visual inspection of the facility utilizing presumptive techniques to identify areas and work practices that may require a corrective response action or exposure assessment.
  2. Presumptive Exposure Assessment - initial determinations of the potential for employee exposure based upon the presumptive guidelines of the Standard.
  3. Site-Specific Written Compliance Program - based upon the audit, addressing the assessment, planning, strategy, and response to the applicable employee exposure, work practice, and administrative control elements of the Standard.
  4. Employee Awareness Training - addressing the required components of the Standard, hazard identification, and employer response program.
  5. Hazard Communication Program - a system for communicating the lead hazard to facility occupants, outside vendors, and contractors.

The Standard states, "One of the most important... issues concerns the criteria by which applicability of the standard and of particular provisions of the standard are triggered. The most basic trigger determines whether an employer is covered by the standard at all..." "This interim final lead standard for the construction industry applies to all occupational exposure to lead in all construction work in which lead, in any amount, is present in an occupationally related context... however, where the source of lead is employment related, all exposure to lead is covered by the standard." "This standard... applies to all construction work in which lead, in any amount, is present in an occupationally related context... where the source of lead is employment related, all exposure to lead is covered by the standard [emphasis added]... ", OSHA 29 CFR §1926.62, May 4, 1993.

APPLICATION OF THE STANDARD

The standard is applicable if a potential source of lead exposure is present in an "employment-related" context. The trigger mechanism for application of the standard is an activity that-- by it's inherent nature-- may cause exposure to lead. Prior to the start of a work activity, the employer is required to make an "...initial determination of the presence of lead." This must be performed if a "potential lead hazard" exists during: work tasks performed "in the presence of lead", occupational exposure to "lead, in any amount", work tasks performed when "lead or materials containing lead are present", work tasks performed in "the presence of lead or in other materials being worked on", "lead containing coatings or paint are present", or "paint dust".

Since there can be confusion concerning a covered work activities, the Standard lists a number of employment categories and project types that in the presence of lead, are high-risk and must be addressed as presumed exposures. Additionally, seventeen specific work tasks are incorporated by reference into the Construction Standard and automatically require a response.

PRESUMPTIVE EXPOSURE HIERARCHY

When any of these activities are performed in the presence of lead-- whether by the facility owner's employees, or outside vendor personnel-- the Standard is applicable.

Level One - Task Related Triggers: The Lead Standard creates a list and description of tasks that automatically require protective measures, prior to establishing the level of potential lead exposure. These tasks are divided into three classifications based upon the potential risk of exposure. Level One tasks are typically encountered during maintenance activities.

Level Two - Employment Activity Related Triggers: The Standard lists a multitude of industries and occupations that are covered, provided lead is present. It is not a requirement of the Standard that the employment related activity always results in exposure to lead, rather the potential existence of lead is sufficient to trigger inclusion. Such work includes but is not limited to: "Construction work is defined as work involving construction, alteration and/or repair, including painting and decorating."

Level Three - Project Related Triggers: The work activities that result in lead exposure are often associated with particular types of projects, so the Standard identifies classifications of projects that typically indicate the potential for exposure to lead. "Construction projects involving lead or lead-containing materials occur throughout the entire construction industry as well as in several non-construction industries... Project type is often a better indicator of the likelihood of lead exposure than the industry classification of the firm performing the work."

EMPLOYER'S REGULATORY RESPONSE INITIATIVE

Facility Compliance Audit A visual inspection of the facility utilizing presumptive techniques to identify areas that may require a corrective response action, and an identification of work practices and activities combined with an assessment of potential employee exposure.

Site-Specific Written Regulatory Response Program

Based upon the audit, the Response Program addresses the assessment, planning, strategy, and response to the applicable elements of the Lead Standard. The Standard specifically requires the development, implementation, and introduction of a facility Written Compliance Program prior to the start of any covered work activity that will result in exposure above the PEL. Not only must the plan be written as site-specific, but it must document the control methods chosen, how they have been instituted, and the future control plans. It must discuss the strategy, goals, problems, and completion milestones for worker protection. Additionally, the Compliance Program must present the alternatives considered but not implemented, and provide the reasoning for the chosen protection and control solutions.

Employee Awareness Training

"Employee Information and Training... The final standard requires the employer to provide an information and training program for all employees exposed to lead at or above the action level. Information and training are an essential aspect of the overall protection of employees who can do much to protect themselves if they are informed of the nature of the hazards in the workplace. To be effective, an employee education system must apprise the employee of the specific hazards associated with his work environment, protective measures which can be taken, and his rights under the standard... The training program required under paragraph (i)(2) must be provided prior to the time of initial job assignment or prior to the startup date for this requirement, whichever comes last, and must be repeated at least annually for covered employees unless exposure at or above the action level will no longer occur."

Hazard Communication Program

A system of information transfer and downstream communication of the lead hazard to facility occupants, outside vendors, and contractors.

"OSHA views the requirement for written plans as an essential part of the compliance program since it will form the basis for determining the employer's ability to achieve the controls and provide the necessary documentation to employees and their designated representatives of the compliance methods chosen, the extent to which controls have been instituted, and of the plans to institute further controls." - OSHA §1926.62

7. ASBESTOS RISK MANAGEMENT SERVICES

All owners and occupants of buildings containing Presumed Asbestos-Containing Materials ("PACM") or Regulated Asbestos-Containing Materials ("RACM") are faced with the management objective of minimizing and controlling the potential asbestos health hazard risk. For a majority of clients, these risk management objectives include: risk management reduction of corporate liability exposure due to the presence or disruption of regulated asbestos-containing materials, regulatory compliance that is effective and efficient management of operations in accordance with Federal, State and Local compliance agency guidelines, and financial management to minimize the financial impact and controlling the timing of asbestos related activities.

Recent regulatory compliance requirements - such as the EPA "Green Book", NESHAP Asbestos Regulations, ASHARA training requirements, and revised OSHA Asbestos Final Rule - have now given building owners the option of maintaining their asbestos in place through management system we at Aerotech Environmental Consulting, Inc. term a comprehensive Asbestos Risk Management Program. Effective risk management is a series of eight steps:

  1. Initial PACM Hazard Identification and Exposure Assessments
  2. Development of Written Management Programs
  3. Worker and Occupant Awareness Training
  4. Emergency Response Planning
  5. Development of Asbestos Materials-Handling Specifications
  6. Execution of Asbestos Related Response Actions
  7. Independent Third Party Air Monitoring
  8. Periodic Reassessment, Audit Control, and Reinspection

ASBESTOS SURVEYS

Aerotech Environmental Consulting, Inc. is a leader in the asbestos survey field.

WRITTEN MANAGEMENT PROGRAMS

Incorporating the information developed from the initial PACM facility survey along with the requirements of the EPA "Green Book" Guidance Document protocol and OSHA Asbestos Final Rule, a site-specific Operations and Maintenance ("O&M") Program will be developed for ongoing operations. The O&M Program manages the asbestos health risk in-place. The site-specific O&M Program includes methodologies to maintain RACM in good condition, ensure proper response, prevent further releases, and monitor the condition of the PACM. The O&M program is developed in consultation with building management. It is written to address the specific needs and concerns of each facility. In conjunction with your management staff, the Program decisions are made to reflect your concerns and tolerance for risk.

Moreover, Aerotech will insure that your O&M Program includes the tasks required by the regulations, but does not engage in needless of unnecessary policies or procedures that add expense without decreasing the resultant asbestos exposure risk,

ASBESTOS-RELATED RESPONSE ACTIONS

Crucial to the minimization of liability and the financial effectiveness of any asbestos related activity within your company's facility, is the thorough implementation and execution of your company's asbestos specification by all involved parties. The best way to ensure attainment of these objectives is through professional on-site project management. It then becomes the Project Administrator's contractual obligation to monitor and document the activities of the abatement contractor. Aerotech Environmental Consulting, Inc. offers your company properly trained, licensed and experienced representation on site during asbestos-related activities.
