NEWS AND PERSPECTIVES FROM DVIRKA AND BARTILUCCI CONSULTING ENGINEERS, YOUR ENGINEERING RESOURCE.

The ockland ounty olid Wasteanagement uthority is responsible forproviding environmentally sound andeconomical management of municipal solid waste and wastewater treatment biosolidsresiduals generated within ockland ounty.In order to accomplish this mission, the uthority utilizes its waste managementfacilities, which include a olid Waste Transfertation, aterials ecovery acility (MRF),and iosolids ocomposting acility, alllocated in the Village of Hillburn, in theTown of amapo, ew ork.

The uthority’s Transfer tation receivesmunicipal solid waste delivered frommunicipalities within the ounty. Wastereceived at this facility is re-loaded intotransfer trailers which are used to transportthe waste to landfills throughout ew ork.

The aterials ecovery acility receivessource-separated recyclable materials, andfurther separates the materials into paper,metal, plastic, and glass components, andenhances the value of these materials by removing residue and compacting thematerials into bales for transport and sale torecyclable material markets.

The ocomposting acility accepts biosolidresiduals from ockland ounty’s publicly owned wastewater treatment facilities andother publicly owned facilities located inneighboring Orange ounty. iosolidsreceived at the facility are composted inaccordance with the requirements of the ew ork tate epartment of nvironmentalonservation (NYSDEC) solid waste

regulations and the facility’s permits so as toproduce marketable compost products suchas soil amendments for landscaping andathletic fields.

s the uthority’s onsulting ngineer since1989, virka and artilucci onsultingngineers (D&B) has been instrumental in theplanning, implementation, and ongoingoperations of these facilities. ’s serviceshave included managing the technical aspectsof the development of the MRF, ocompostingacility and Transfer tation improvements.

The MRF and ocomposting acility beganoperations in 1998 and 1999, respectively.uring 2004 and 2005, D&B assisted the

uthority in procuring private, full-serviceoperation and maintenance services for theocomposting acility, and assisted the

uthority in the development of a full service agreement between a private operator and the uthority.

In ay 2005, based on an extensive evaluation and negotiationprocess, We are Organics, LLC, was selected to operate andmaintain the ocomposting acility and to implement facility upgrades and improvements.

The facility improvements, which had a total project cost inexcess of $ .7M, included process improvements, odor controlimprovements, building structure improvements, as well asenergy efficiency improvements. Process and odor controlimprovements included equipment overhaul, equipmentreplacement, instrumentation and control system upgrades,and replacement/upgrade of consumable materials such asammonia scrubber packing and biofilter media. The projectconsisted of more than 5 distinct tasks covering the variousaspects of the overall project. The tasks varied in size andcomplexity, with one of the largest tasks, in terms of cost andcomplexity, addressing the deteriorating building structure.

S ruc ur d r or o d corros o of s roof ms.

In 2005, building structure components, including columns, beams and purlins, which make up the support of the roof

structure of the building, had experienced extensive corrosioncaused by the highly humid and ammonia-laden atmospherein the building, particularly in sections where the compostingprocess occurs. Prior attempts to correct this problem by applying corrosion-resistant coating systems wereunsuccessful. The coatings rapidly failed under the severeconditions within the building, leaving the structural steelexposed to further corrosion. different approach wasneeded to arrest the corrosion before the building’s structural

integrity became compromised. investigated andevaluated possible solutions to this problem and ultimarecommended a proprietary corrosion control and therminsulation system developed and supplied by Prefeolutions, Inc.

The coating system consists of a layer of foam insulacovered with a chemical resistant air and moisture barThe barrier coating is a patented polyurea hardcoat layer the trade name tayflex. The coating system covers encases the columns, beams, purlins, and connections wmake up the building structure, encasing and isolating athe structural components from the atmosphere within building.

Prior to installing this system, a structural assessmentmade of the building structure. tructural upgrades wperformed so that all components which were not going tencased in the coating system, such as pipe and lighhangers, were replaced with stainless steel components. project was planned and scheduled to minimize the facshutdown time and the requirement to bypass biosolid

alternate facilities, which was a significant cost to the utho recent inspection of the entire coating project, after mthan one year in operation, indicated excellent performa with no further corrosion or deterioration. In additioncorrosion protection, the coating system provides an insula value of 7.7 per inch.

ultimately recommended to the uthority, a patentedsystem supplied by onserval ngineering, Inc., known by the trade name olarwall.

olarwall is a dark colored corrugated metal siding which isperforated with small air inlet holes. The metal is strategically placed on the building exterior so as to optimize exposure tothe sun. The olarwall is mounted on the building exterior walls to create an interstitial space between the olarwall andthe existing building siding. xisting building ventilation fansare utilized to draw air through the olarwall perforations.The heated air from the surface of the olarwall enters thespace between the olarwall and the building siding. The warmed air travels from this space into an inlet duct into the building, where the heated air reduces fuel oil consumed forspace heating.

olarwall was installed on three separate walls of thecocomposting facility building so as to supply space heat totwo independent building heating systems located on oppositeends of the building.

The olarwall project was completed in eptember 2007.oth the olarwall and tayflex provide energy conservationand greenhouse gas reduction benefits through olarwall’scapture of solar energy and tayflex’s insulating properties.uel savings have not yet been quantified, although thefacility operator has reported a reduced reliance on fuel oil forspace heating.

In addition to the innovative and “green” features includthis project, D&B specified the use of recycled content prod for the Administrative Offices and Records Storage uildingincluding carpet and floor tiles made from recycled material

In addition, D&B specified the use of recycled conaggregate as ground cover around the ocomposting aciliand MRF, as well as in the yard waste composting pad.

ocomposting acility operations have been excellent sincompletion of the improvement projects. ll biosoldelivered to the facility have been processed to prodmarketable compost, without the need for any bypassinalternate facilities or disposal. There have been necapacity constraints nor system failures which could required costly bypass of materials. Odor complaints h

also decreased significantly. The building structure remin good condition, with no further corrosion or deterioratand the use of fuel oil for space heating has been redu With continued proper operations and maintenance, facility should continue to provide the uthority aockland ounty a long-term solution to handling i
