 Project: Site Design for Commercial Strip Center 3,750 ft2 Building 23,000 ft2 Site


Scope of Work: Provide Site Design and Permitting for existing commercial property within City of Tampa's Development area. Site Development and Permitting required City of Tampa Commercial Development, Wastewater and Water Design Review, Southwest Florida Water Management Individual Environmental Resource Permitting and The Florida Department of Transportation Access and Drainage Permitting



EEC was retained to provide Site Engineering Plans and Permitting for a Small Strip Center within the City of Tampa's Limits. Site Design incorporated parking, landscaping, stormwater, water and wastewater connection design. Full access from a Florida Department of Transportation major arterial access was restricted to entry only. Prior access was a full access from the FDOT road. The modification to the access required connection to a residential side street with restricted access for left only traffic. Due to a residential setting behind the commercially zoned parcel the site required a variance to allow restrictive building setbacks be modified for this development.


Stormwater Design criteria was based on the most restrictive requirements of three different Permitting Entities. Based on FDOT guidelines which were the most stringent of the Permitting Entities (COT, SWFWMD and FDOT), connection to the FDOT drainage System was acquired. To provide a functional but aesthetically pleasing look to the Stormwater Management System a low profile perimeter fence design was incorporated into the basin layout.


EEC also provided construction monitoring, inspection oversight and As-built preparation and required permitting closure for the completion of this Project.

 Project: Industrial Wastewater Pumping Station and 1,600 ft Forcemain Jack and Bore


Scope of Work: Provide Site Design and Permitting for existing commercial property to the City of Tampa's wastewater system 1,600 ft Forcemain within a Hillsborough County and jack and bore CSX right of way.



EEC was retained to provide Site Engineering Plans and Permitting with the City of Tampa wastewater Division, the Environmental Protection Commission of Hillsborough County Wastewater Division, Hillsborough County Right of Way and CSX for a commercial meat packaging center.


The existing Site's connection was dependent on acceptance from the City of Tampa for an existing older Forcemain which had no clear ownership or easements in place to allow the City's approval for connection. Routing of the Forcemain by means of any other connection route was not economically feasible but connection for the commercial meat packaging center was imperative.


EEC provided extensive research of deeds and utility line placement within the area noted for Forcemain placement. The forcemain connection also crossed under a CSX main line track which required Permitting and construction oversight through CSX via a 90 foot Jack and Bore under CSX Right of Way limits.


Connection to existing forcemain required 900 feet of line be strategically placed to accommodate the existing 36 inch concrete drainage culverts and numerous other utilities running the length of the Right of Way. To traverse line crossings of the Concrete Drainage culverts (2) air release valves were placed within the forcemain layout to accommodate low points at those culvert crossings.


Completion of the Project will require EEC provided construction monitoring and As-built preparation of the Forcemain connection.

Project: Gandy Blvd Commerical Center Wastewater

Pumping Station and Forcemain


Scope of Work: Provide Site Design and Permitting for existing commercial property to connect to the City's wastewater system within Gandy Blvd, a Florida Department of Transportation's major arterial running within City's Limit's.



EEC was retained to provide Site Engineering Plans and Permitting concerning a Private Pumping Station and Forcemain connection to the City of Tampa's Wastewater System located within the Florida Department of Transportation's Gandy Blvd. Right of Way. Placement of the connection was a challenge due to traffic volumes as well as construction costs for milling and resurfacing of a major arterial.


Permitting of the Forcemain required on-site Septic closure and Lift Station design through The Environmental Protection Commission of Hillsborough County, Florida Department of Transportation Right of Way Permitting and Maintenance of Traffic design, and City of Tampa Wastewater Department review and acceptance of Forcemain design.


EEC also provided construction monitoring and As-built preparation and required permitting closure for the completion of this Project.

Project: Manufacturing Facility Production Room Expansion

Scope of Work: Evaluate proposed Flammable and Combustible liquids and mixing operation requirements. Modify existing warehouse for compliance with NFPA regulations. Assist in the Site design for placement of new exterior aboveground double-washed Liquid Product Storage Tank as well as (2) Dry Mix Silo's.



EEC was retained by a private manufacturer of decorative concrete overlays to evaluate and modify the existing Fire Suppression System for compliance with new NFPA regulations. The new chemical mixing facility would contain highly Flammable and Combustible emulsions which required the fire prevention and control provided for this facility be determined by means of an engineering evaluation of the operation and application of sound fire protection as well as process engineering principles.


EEC in collaboration with an Electrical, Structural and Fire Protection Engineer proposed modifications to the existing warehouse which will provide the required safety yet cost effective compliance with new NFPA regulations for Flammable and Combustible liquids and disposal of wastewater generated by the Fire Suppression process.


To address maximum product storage under NFPA guidelines within the new facility an outdoor product storage tank area utilizing a double walled above ground storage tank to dispense measured product to mixing facility was laid out. To further facilitate the expanding facility dry product storage was also addressed by Site design and placement of (2) outdoor Silo's, including FDEP Air Permits.

Project: Industrial Aggregate Mixing Plant

Scope of Work: Industrial Air Testing and Permitting


​An example of an Industrial Air Testing project would be when Environmental Engineering Consultants, (EEC) performed an Environmental Protection Agency (EPA) Method 9 Visible Emissions (VE) Testing at a soil cement plant in Bradenton, Florida.  The test was conducted while the cement silo was being loaded with Portland cement.  The process was observed to be in dust emission compliance with applicable limitations.  The average opacity and the greatest six-minute average were observed to be 0% for the emission unit.  The rock crusher, cement plant equipment and all transfer and drop points were observed to be in compliance with applicable emission limitations.  All tested sources showed a 30-minute and maximum six-minute average opacity of 0% Shaker Exit, and Finished Product drop point both had 30 minute VE Test performed and were determined to be in compliance.

Project: Industrial Grain Processing Facility

Scope of Work: Industrial Air Testing and Permitting


​EEC was retained to perform Industrial Air Testing and Permitting at a grain facility in Florida. Analysis revealed that the maximum total material transfer rate for the port material handling systems combined was not exceeded for a 12 consecutive month period. The maximum production rate is about 300 tons per hour; two loading spouts, a partial enclosure and the use of a water mist around the enclosure area were utilized and needed to control emissions. Particulate matter emissions from the railcar/truck loading station needed to be controlled by a telescoping spout with a loading boot. The telescopic spout would then be positioned and extended to minimize the drop height during loading. The ship’s hatch needed to be kept partially closed, as much as practical, during ship loading operations to reduce the release of particulate matter emissions. In addition to these elements, EEC suggested that tarps be used, as necessary, across the open sections of the shiphold during loading in order to meet the required opacity limitations. Finally, caution must always be utilized when cleaning out the shipholds to minimize the generation of dust in a coastal sensitive environment.


Project: Mulberry Materials Recovery Facility

Scope of Work: Solid Waste Design


This project required taking an existing industrial building in Mulberry, Florida and redesigning it as a Construction and Demolition Debris Recycling Facility. The solid waste stream was designed to be brought in and sorted on a concrete slab for recovery of materials of value. The remaining waste was to be loaded into haul dumpsters for transport to the Polk County Landfill near Fort Meade.  An Operation Plan was prepared for the flow of material and submitted as part of the permit application to the FDEP.  This also included an Environmental Resource Permit (ERP) being applied for and issued by the FDEP to properly handle storm water runoff from the facility. The FDEP issued a Materials Recovery Facility (MRF) Construction permit for the project. The project has not been constructed due to proper financing being withheld due to the economic recession.

Project: Hi-Tech Laboratory Industrial Wastewater Pretreatment Facilities

Scope of Work: Wastewater Compliance


EEC was retained by a private laboratory in New England to provide municipal permitting of an Industrial Wastewater Pre-Treatment Facilities located in St. Petersburg, Florida. The wastewater stream from this hi-tech research and development laboratory was treated with pH adjustment, solids and carbon filtration, ion exchange and flow measurement.  In addition to obtaining permitting from the City of St. Petersburg, EEC was retained to perform construction oversight and start up consulting. EEC was also requested to provide bi-weekly operation inspections and to work with the on-site maintenance staff. In 2011, EEC was again asked by the same laboratory to provide similar services in Tampa at the new research facility located near USF.   This system began operation in 2012 and was permitted by the City of Tampa.

The rinsate wastewaters involved with such processes are directed to an on-site wastewater pre-treatment system which treats the influent wastewaters making it compliant to pump into the City of Tampa and City of St. Petersburg wastewater collection systems. Pre-treatment processes used in treating wastewater includes: sediment and carbon filtration, ion exchange, pH correction, and air mixing. A remote alarm system is linked to monitored parameters pH, conductivity, flow, and water leak detection. EEC performs bi-weekly operation and maintenance for both of these wastewater pretreatment systems.
