Overview – Green and Sustainable Remediation

Green vs. Sustainable Remediation

Principles of Practice, Policies,Guidance and Standards

ASTM Standard Guide forSustainable and Greener Cleanups

Green Remediation Technologies

The Future– What we expect from a regulatory

perspective?– Where are the business

opportunities?


Green Remediation

Green Remediation – in general, incorporatesenvironmental factors– Environmental factors are generally considered to be the

following elements: energy, air emissions, water impacts,material and waste, and land and ecosystem

– A green remediation project incorporates various activitiesrelated to optimizing the various elements

• However, the implementation needs to be above and beyondwhat would be considered standard practice

– Only considers economic and societal factors to the extentrequired by existing regulatory requirements

– Level of analysis can vary from screening level evaluation tofull blown life cycle assessment


Green vs. Sustainable Remediation

Green Remediation– EPA Definition: “The practice of considering all

environmental effects of remedy implementation andincorporating options to maximize net environmentalbenefits.”

Definition of Sustainable Remediation– SURF Definition: “Sustainable remediation is broadly defined

as a remedy or combination of remedies whose net benefiton human health and the environment is maximizedthrough the judicious use of limited resources.”


Sustainable Remediation Triple Bottom Line Accounting

– Environmental Factors• These are better established, namely because

these can be evaluated from a technicalperspective by environmental professionals

– Economic Factors• From a cost perspective, these can be

evaluated; however, evaluating the economicvalue brought to the community is more difficultto measure

– Societal Factors• Screening level analysis is relatively

straightforward; however, quantitative analysisis difficult

Level of analysis can also vary fromscreening to full-blown life cycle assessment

Focused on principles, outreach, information disseminationand study of the practice

Discussion of metrics

Framework document, but not a recipe for action


ASTM Green & Sustainable CorrectiveAction Standard Practice

Most likely to become industry standard adopted by EPAand states

Will not be a stringent practice standard, but will be a guideby definition

To incorporate environmental, societal and economicissues on a flexible basis

Likely to be a tiered approach – screening, qualitative &quantitative tier options

Draft standard will not be complete for at least one year


ASTM Framework for Green & SustainableRemediation

Green & Sustainable Remediation is a Process, not aTechnology– GSR principles should be integrated into cleanup projects– Applied on a phase-by-phase basis– Is not just about green technologies– Best management practices that are

incorporated into projects


ASTM Standard Guide Outline

Purpose of Standard Guide How the Standard Guide is Being Developed Structure

– Green Remediation– Sustainable Remediation

• Green + Economic & Social

– Tiered Evaluation• Qualitative Evaluation (Best Management Practices)• Quantitative Evaluation (Numerical)

– Standard is applied on a phase-by-phase basis1. Site Assessment2. Remedy Selection3. Remedy Design and Implementation4. Operation, Maintenance and Monitoring5. Remedy Optimization


Management Practices (ASTM Standard)

Standard Management Practice– A practice that you are considered industry standards

and are truly basic in nature• Recycling office waste• Using compact fluorescent light bulbs• Minimizing paper use with electronic filing systems

Best Management Practice– Activity that improves the environmental, economic, or

social aspect of a cleanup project or the site itself– ASTM is developing a list of both basic BMPs and

significant BMPs• Significant is a BMP that requires an increased level of effort and

results in a greater net benefit


ASTM Standard Guide – Green Remediation

Best Management Practices– BMPs drive sustainable remediation– BMPs are organized on a technology or activity basis, but are

applied based on the phase of the project– Green BMPs follow EPA’s five core elements

1. Energy2. Air Emissions3. Water Impacts4. Material and Waste5. Land and Ecosystem

– ASTM is attempting to establish a “bar” for the minimumnumber of BMPs that need to be incorporated into a project inorder for it to be considered Green or Sustainable


ASTM Standard Guide Process

Two Tiers of Evaluation– Qualitative– Quantitative

Qualitative Evaluation has a 5-Step Process1. Standard management practice review and selection2. Best management practice opportunity assessment and screening3. Best management practice screening4. Best management practice implementation5. Measurement and documentation

Green Remediation – Quantitative Analysis

Two Types of Quantitative Analysis1. Environmental Footprint Analysis2. Life Cycle Assessment

Purpose of Quantitative Analysis– Technology Evaluation

• Use to compare metrics between different technologies– Quantify Metrics

• Develop methodology for calculating net environmental benefits– Opportunity Evaluation

• Identifying where the biggest net benefits are within a project


Life Cycle Assessment


ASTM’s Sustainable Remediation Track

The Sustainable Track = Environmental + Economic/Social Sustainable Core Elements

– Collaborative participation– Community livability– Individual quality of life– Net economic benefits– Economic risk reduction

Quantitative Metrics– Increased wages to the community during remediation– Jobs during and following remediation– Resources purchased locally– Other social or economic benefits– Environmental metrics/benefits (lower risk, fewer emissions,

other core elements)


Green Remediation Applications – Pump &Treat Environmental Factors

Groundwater Extraction– Energy, materials, water, dewatering effects

Air stripping– Energy for blower– Materials for cleaning stripper

Off-gas Treatment (Granular ActivatedCarbon)– Air emissions– Materials (GAC)– Waste (GAC)

Discharge to Surface Water– Net water loss

Building Operations Long-Term Operations Fact: 1 hp uses 240K kWh over 30-year

period


Pump & Treat Technology – Greening Consider Source Control Technologies to Limit Time of Applications Alternative Energy Use

– Solar or wind either sourced onsite or offsite– Use variable frequency drives instead of throttling

Groundwater Extraction– Consider pulsed system operation– Manage flows– Replace water via injection

Air stripping– Energy for blower– Materials for cleaning stripper

Activated Carbon– Regenerate instead of disposing

Materials & Supplies– Source from local vendors– Recycle as much waste as possible

Discharge to Surface Water– Net water loss

Building Operations– LEED aspects, recycling, energy efficiency, building materials


BP Paulsboro Pump & Treat System



Uses a 275-kW solar field to power pump-and-treat (P&T)system extracting 300 gallons of ground water per minute

Solar energy used to operate six recovery wells, includingpump motors, aerators, and blowers

Transfers extracted ground water into a biologicallyactivated carbon treatment system

Obtains 350,000 kWh of electricity, which meets 20-25% ofthe P&T system's energy demand

Eliminates 571,000 pounds of CO2 emissions annually Prevents emission of 1,600 pounds of SO2 and 1,100

pounds of NO2 each year Site is being redeveloped as a port facility


What does the Future Hold for GSR?

How will GSR be incorporated into regulatoryframeworks?– Guidance, policy, or regulation?– Federal or provincial level?

What other government drivers may be utilized?– Government contracting– Governmental orders– Sunfields and windfields– Tax incentives– Grants– Carbon credits– Natural resource and wetland banking


What does the Future Hold for GSR? (cont.)

What are future business opportunities for GSR?– Drive remedy selection on an ad hoc basis?– Will ASTM standard be incorporated into regulations or

guidance?– Will GSR be included in federal, provincial, local, and

private investigation and remediation solicitations?– Will new products be developed?
