Permitting Compliance – WEG Engineering personnel have extensive experience in assisting clients with their permitting and compliance issues. WEG conducts environmental compliance audits for industrial, commercial and governmental facilities to assist in achieving and maintaining compliance with environmental laws and regulations. Normally, this consists of evaluating the facility needs and operations, determining the applicability of permitting, preparing applications, or compiling data for permit preparation, submission, maintenance, sample collection and analysis, and monitoring. WEG assists with permitting for water and wastewater discharges, solid material and waste storage, transportation and disposal, and air emissions to maintain compliance with applicable federal, state and local regulations and guidelines.

Permit Acquisition for the construction of new emission sources, operation of existing or modified sources, and compliance evaluation. Industrial process and stormwater discharge permitting assistance for National Pollutant Discharge Elimination Standards (NPDES). Preparation of permit applications, renewals and modifications, regulatory agency correspondence and negotiations, and sampling and monitoring of discharges.

Environmental Compliance Audits of facility procedures and documentation to identify potential deficiencies with regards to federal, state and local rules and regulations pertaining to waste handling and disposal, regulated storage tanks, air and water discharges, reporting, permitting or other site-specific requirements. Audit findings are then evaluated and recommendations are prepared for corrective action.

Turnkey Bioremediation – WEG provides turnkey remedial services (investigation, design, implementation, operation, monitoring and closure) for in-situ and ex-situ bioremediation. Ex-situ remediation projects consist of lined cells (biocells) in which soils excavated from the contaminated areas are placed for treatment. In-situ projects treat soils and groundwater in place.

WEG begins with a Bioremediation Feasibility Study (BFS) to be sure that the compounds of interest will be degraded and that no other compounds are present that will inhibit microbial growth. WEG supplements oxygen or other electron acceptors as necessary, and monitors and maintains nutrients, soil moisture, pH, dissolved oxygen and microbial population. Bioremediation has been shown to be successful on petroleum hydrocarbons, chlorinated solvents and glycols with new strains of bacteria being developed to treat even more contaminants. Because of its cost-effectiveness, bioremediation will continue to grow as a preferred remedial technology.

Facility Plan and Report Preparation – WEG has experience with reporting requirements and preparation of facility plans and reports for submittal to federal, state and local regulatory agencies. WEG has completed hundreds of reports for various private, industrial, commercial and governmental clients. Examples of some of the facility plans and report formats are summarized below:

Subsurface Soil Groundwater Investigation – WEG Engineering’s professional engineers, hydrogeologists, chemists and environmental scientists have conducted numerous subsurface soil and groundwater investigations (both scheduled and on a "round-the-clock" emergency response basis) for remedial investigation/feasibility studies and characterizations of the nature and extent of subsurface contamination using drilling, monitoring well installation, hydropunch, geoprobe, soil gas surveys, soil and groundwater sampling, field testing and laboratory analysis, fracture trace analysis, surveying, geophysical studies and hydraulic testing.

WEG’s team of engineers and scientists have extensive experience with environmental investigation and analysis to characterize the degree and extent of contaminants in surface soil, subsurface soil, groundwater, surface water and sediments. Given a measured concentration of a chemical or contaminant, we utilize scientific principles and computer modeling to assess whether or not the contamination poses a threat to human health or the environment. If a threat is present, WEG designs appropriate, cost-effective engineering controls to either remove the contaminants or immobilize them in accordance with state and federal regulatory guidelines.

Remedial Design Risk Assessment – When contaminant concentrations in soil and groundwater exceed default statewide health standards, WEG utilizes risk assessment procedures to determine site-specific health standards based on actual uses of the property, and to evaluate whether contaminants found in the environment constitute potential threats to human health or the environment. The risk assessment includes identification of compounds, degree of exposure, dose-response and risk characterization. WEG uses ASTM Risk-Based Corrective Action (RBCA) procedures for petroleum hydrocarbon impacts and the US EPA’s Risk Assessment Guidance for Superfund (RAGS), as amended by changing EPA policies and common practice. Risk assessments frequently result in site-specific action levels that are not exceeded by measured site concentrations of contaminants resulting in "no further action." WEG also assists clients in risk communication to help explain the complex calculations to regulators and/or the public.

However, when remediation is necessary, WEG evaluates applicable technologies to determine the best remedial method to meet the client’s financial constraints while satisfying statewide or site-specific action levels. A remedial design is then developed to implement the selected remedial technology. Many factors are considered during the remedial technology evaluation and design. These include cost (capital, maintenance, monitoring and operation), liability, duration, facility/production disruption, salvage value and probability and success. A few technologies WEG is experienced with include groundwater recovery, air stripping, aqueous or vapor phase carbon adsorption, in-situ and ex-situ bioremediation, controlled excavation and disposal, incineration, oil/water separation and low temperature thermal desorption.

Finally, a unique characteristic of WEG is that we routinely perform the actual construction/installation, operation, maintenance and closure of the remedial technologies in house. This allows our design engineers to receive direct feed back on the practicality and effectiveness of their designs.

Careful evaluation and interpretation of field data is an extremely important aspect of site investigations. WEG combines soil and rock information from boring logs; water levels from monitoring wells and surface water bodies; hydraulic properties calculated from aquifer tests; and contaminant distribution data from field and laboratory analyses to create a consistent conceptual model of the geology, hydrogeology and contaminant transport for a site.

Environmental Auditing – An environmental audit may safeguard your business from violating environmental laws and regulations. When the regulatory agencies come knocking on your door, your response will simply be, "we already have it under control."

What is an environmental audit?

·	An environmental audit from WEG Engineering is a thorough, compliance and regulatory based, multi-media assessment of your facility performed by our experienced staff of scientists and engineers. It is designed to identify potential or existing environmental concerns and verify compliance with existing rules and regulations.
·	The importance of this self-evaluation is to let you know where your facility stands on compliance with regulatory issues. You should know if you are in violation and what, if any, fines could be imposed.
·	The document provided to you is NOT submitted to the regulators.

Why should you have an environmental audit?

·	By voluntarily addressing environmental concerns and non-compliance, you reduce the risks associated with liability in the future. Spending a small amount of money now may save your company the exorbitant costs associated with potential fines and penalties in the future.
·	Efficient companies, local governments, and privately owned businesses conduct environmental "inspections" to keep them in compliance with laws and regulations.
·	Routine monitoring is one of the best ways to assure compliance and benefit the environment allowing for planning and is more cost-effective than reacting to a regulatory agency inspection.
·	Finding the problem on your own can prevent potential penalties.
·	If a voluntary audit is NOT performed and the regulatory agency finds a violation, there is no protection from fines or penalties.
·	EPA will not recommend criminal cases be brought against businesses that voluntarily disclose violations.
