Oasis Consulting Services Named Winner of 2018 ACEC Engineering Excellence, Environmental Award

On November 1st, 2017, the American Council of Engineering Companies of Georgia (ACEC – Georgia) announced the recipients of the 2018 Engineering Excellence Awards. Oasis Consulting Services was named the recipient of the 2018 ACEC Georgia Engineering Excellence Award, Environmental Category for the Baldwin County Landfill – Phase 3 closure project.

The Baldwin County Landfill was the first of its kind in the state of Georgia to utilize the ClosureTurf® system in lieu of a vegetative cap — saving the county thousands of dollars in initial and long-term costs. In 2016, Baldwin County Board of Commissioners sought a design-build option for the closure of the 21.5 acre, Phase 3 Union Hill Church Road landfill. Oasis Consulting Services, a metro-Atlanta based woman-owned engineering consulting firm, was awarded the contract and obtained the Georgia Environmental Protection Division (EPD) approval of ClosureTurf.

Report from July 10, 2017 Georgia EPD HSRA Stakeholders Meeting



The Georgia Environmental Protection Division (GEPD) Land Protection Branch hosted a stakeholder meeting on July 10, 2017 to discuss the proposed rule changes for the calculation of environmental cleanup standards in accordance with the Rules for Hazardous Site Response.  Representatives from Oasis Consulting Services attended this meeting to review and comment on these proposed changes.  During this meeting, proposed changes to the rules themselves were presented as a redline document, and both proposed changed to the existing default Risk Reduction Standards (RRS – the HSRA defined term for cleanup levels) and changes to the specifics for calculating site specific RRS were discussed and presented in tables for stakeholder review.  GEPD will be accepting comments on these proposed changes, and they will subsequently be presented to the Georgia Department of Natural Resources (GDNR) board for approval.  If they are presented and approved later this year, it is expected that these changes will be rolled out sometime in 2018.



The proposed changes involve revisions to both the default and site specific RRS used to determine the need for corrective action for properties on the Georgia Hazardous Site Inventory (HSI).  The default residential and non-residential RRS (Type 1 and Type 3) will be revised based on toxicity data (and published online rather that in the rules directly), which has changed since the original rule was adopted in the late 1990’s.  The revised Type 1 RRS for soil will not include the potential to use the Type 1 groundwater RRS times a factor (100) as a possible RRS.  When looking at these proposed changes, we see that some of the RRS will decrease (chlorinated solvents in particular), and some will increase.

Generally, this may force more responsible parties to use Type 2 and 4 (Site Specific) RRS to both determine initial compliance and to develop reasonable cleanup criteria for corrective action. Fortunately, there are also significant changes in the determination of these site specific RRS as well.  The existing rules have a complex decision tree used to determine Type 2 and 4 RRS which considers acute and chronic toxicity, exposure pathways, and for soil, leachability, determined by TCLP or an approved alternate leaching protocol.  These ‘calculated’ values also mandate the use of GEPD defined exposure criteria – criteria that mandate considerations that are in many cases unrealistic like considering all groundwater as a potable source.  As a result, the existing ‘site specific’ RRS in many cases give responsible parties unrealistic and untenable cleanup criteria. The proposed changes include several revisions to both the use of defendable site-specific exposure criteria (i.e. calculation of a groundwater RRS based on non-potable exposure where such potable use is prohibited or unrealistic).  Also, soil leachability criteria will be revised to include to potential to use actual site data to define leachability – if a site has groundwater that continues to meet the appropriate RRS over time, the existing soil concentrations can in effect be considered as the leachability value.  Additionally, soil averaging studies will be accepted for review in determining direct contact soil RRS compliance.  And, engineering controls will be approved for Type 4 soil and groundwater RRS compliance determinations, unlike the present requirement of a generally difficult Type 5 determination.



The proposed changes to the now about 20-year old HSRA rules generally parallel the progress seen in the environmental cleanup industry since the original rule was issued.  These changes will bring some much needed flexibility to the determination of appropriate site-specific RRS and bring HSRA more in line with both risk based rules in other states and with the current Georgia Voluntary Cleanup Program (VCP).

Oasis Consulting Services Presents at Environmental Show of the South


This week, the Environmental Show of the South was held in Chattanooga, Tennessee — the region’s largest and most comprehensive environmental conference.

Oasis Consulting Services was well-represented by Vice President of Strategic Business Development Michael Monteleone, P.E., who also delivered an insightful presentation. Discussing the topic of “Best Practices for Unmanned Aerial Vehicle (UAV) Turnkey Services,” Mr. Monteleone showcased why Oasis Consulting Services is at the forefront of innovation within the environmental engineering industry.


Baldwin County Breaks Tradition with an Award-Winning Landfill Design

The Baldwin County Landfill marks a historical final closure as not only the first of its kind in the state of Georgia, but one of the first in the country to feature an entirely new landfill design process utilizing the ClosureTurf® system. Featuring an innovative technology, called ArmorFill™, the system eliminated the need for diversion berms, benches and down chutes by completely changing the hydrology methods in the traditional design.

In 2016, Baldwin County Board of Commissioners sought a design-build option for the closure of the 21.5 acre, Phase 3 Union Hill Church Road landfill. Oasis Consulting Services, a metro-Atlanta based woman-owned engineering consulting firm, was awarded the contract and obtained the Georgia Environmental Protection Division (EPD) approval of ClosureTurf in lieu of a traditional vegetated cap.

“We will probably make history. This is the first municipal solid waste landfill that has been closed in the state of Georgia with this process. We already have several individuals from several states that have come down and visited. It will be a showplace for the state of Georgia.” – Ralph McMullen, Baldwin County Manager

With SPLOST funds stretched, the county was relieved that the design-build solution from Oasis came in $1.5 million under traditional procurement. The approved ClosureTurf® system attributed to much of the cost savings. It eliminated the standard USEPA costly, lowpermeability clay liner, as well as vertical in-waste gas collection wells. But the real distinctive advantage was the use of ArmorFill™, an innovation created by Watershed Geo to enhance the hydraulic benefits of ClosureTurf. ArmorFill is an environmentally-friendly binding agent that is added to the top protective sand infill layer of the system. Even with slopes steeper than 3:1 in some locations, ArmorFill allows the entire cap to sheet flow to the perimeter ditches, eliminating the need for diversion berms (used to combat drainage length) and downslope channels (energy dissipation). This cutting edge design ultimately created a domino effect in cost savings and risk management for the county.

“We feel that this system and this process is not only going to save us money, but there is some dirt out there that we can’t stabilize and we could spend hundreds of thousands of dollars going back repairing, cutting grass, etc.,” McMullen said. “Every time you went out there, there would be some other repair.”

Oasis was able to complete the installation in about half of the time required for prescriptive caps. In addition to design and construction savings, future maintenance will be drastically reduced during the long-term post closure care period. The surrounding environment will also benefit, especially water quality, as a result of two key factors: the avoidance of fertilizers that
will not be necessary to grow and maintain grass; and the elimination of soil erosion and sediment-laden runoff from the cap.

As acknowledgement for their innovative approach, Baldwin County and Oasis Consulting Services was awarded the 2017 Georgia Chapter American Public Works Association engineering award for innovative, small/rural community projects.

Woman-Owned Firm Awarded First GEPD-Approved Alternate Landfill Cover in Georgia

ROSWELL, GEORGIA – Oasis Consulting Services, a metro-Atlanta-based woman-owned engineering consulting firm, was recently awarded a turnkey design-build contract for $2.74 million by the Baldwin County Board of Commissioners for a 21.5-acre alternate final landfill cover system.

The system, which uses the patented ClosureTurf® engineered turf, is the first alternate final cover system of its kind approved by Georgia Environmental Protection Division for use on a municipal solid waste (MSW) landfill in Georgia.

Baldwin County, seated in Milledgeville, is a mostly-rural community where the historic first state capitol of Georgia was located. This proven closure solution will enable the county to meet state solid waste rules requirements and state enforcement district requirements, while providing a cost-effective final cap to conserve much-needed SPLOST funds for other important county needs.

The approved ClosureTurf® final cover system eliminates a costly prescriptive clay layer as well as vertical landfill gas collection wells. Additionally, the use of Armorfill™ to enhance the turf sand infill eliminates the need for diversion berms and down chutes, to allow the entire cap to sheet flow to Armorfill™ perimeter ditches.

Representing Oasis Consulting Services as the lead permitting engineer and project manager will be Solid Waste Division Vice President J. Robin “Robbie” Blanton. Mr. Blanton brings decades of experience and innovative design solutions to this venture. In the past, Mr. Blanton has completed successful projects on behalf of Oasis Consulting Services for clients such as the City of Atlanta, DeKalb County, the City of LaGrange, and Virgin Islands Waste Management Authority.

Under the direction of Oasis, the patented system will be supplied by WatershedGeo® of Alpharetta, Georgia, and installed by American Environmental Group Ltd. of Richfield, Ohio. The ClosureTurf® system is expected to be completed in half the time of a comparable standard EPA Subtitle D final cap, and will minimize the county’s post-closure maintenance for the EPA-minimum 30-year post-closure period.
