WASTEWATER TREATMENT AND PERMITTING

The staff at Rodak Engineering has experience in the design, permitting, operation, and monitoring of industrial wastewater treatment systems for a variety of contaminants (metals, petroleum constituents, suspended and dissolved solids, and other toxic organic and inorganic compounds).  In his career in industry, Mr. Rodak was responsible for the overall operation and maintenance of a 30,000 gallons per day (gpd) pretreatment system for wastewater from a zinc/chrome electroplating process.  His duties included supervision of technical personnel responsible for daily operation of the system, monitoring system performance through effluent sampling, development of sampling and maintenance protocols, effluent regulatory reporting, and design and permitting of expansions and upgrades to the system.   He also was responsible for permitting and monitoring wastewater discharges from four other facilities as part of his manager duties.

Our professional staff have designed wastewater treatment systems for fiber optics and textile manufacturers to remove solids, oils and grease, and metals from industrial wastewater discharges.  Our treatment design experiences have incorporated technologies such as ion exchange, oil/water separation, flocculant formation and gravity settling, ultraviolet and chemical disinfection, and solids removal through filtration and reverse osmosis.  We have designed wastewater treatment systems for vehicle maintenance activities at several North Carolina military bases, for domestic wastewater at two North Carolina correctional facilities, and for industrial wastewater from an industrial chemical vapor deposition process.

AIR EMISSIONS TREATMENT, PERMITTING, and MONITORING

The staff at Rodak Engineering has experience in the design, permitting, and monitoring of industrial air emission sources and control devices for Criteria and Toxic Air pollutants. Facilities for which Rodak Engineering staff have provided air permitting, dispersion modeling, control device design and emission monitoring services include cement and asphalt batch plants, fiber optic manufacturers, hospitals, textiles, chemical refineries, auto component manufacturers, rubber manufacturers and furniture manufacturers.

Our staff‘s project experience includes the design of air pollution control device systems for a fiber optic manufacturer to remove hydrofluoric acid, VOCs, and particulate emissions from chemical vapor deposition processes.  Our control device design experience has included technologies such as dry neutralization, baghouse and baffle box filtration, and catalytic oxidation/thermal desorption.

Rodak Engineering staff have prepared annual emission inventories for Small, Synthetic Minor, and Title V facilities in North Carolina.  We have also performed air dispersion modeling for Criteria Pollutants and Toxic Air Pollutants to demonstrate compliance with Acceptable Ambient Levels using EPA dispersion models including SCREEN3, ISCST3, and AERMOD.   We have prepared stack testing protocols, designed emission source capture devices for stack testing purposes, and provided technical oversight of air emissions monitoring from metal annealing, tool coating, and rubber manufacturing processes.  We have prepared stack testing reports and have interacted with regulators in the interpretation of the results and associated permitting modification requirements.

In addition to emission source permitting, control device design, and monitoring services, Rodak Engineering staff also provides indoor air quality and HVAC inspection evaluation services.  We have performed static (fixed) and dynamic (personnel-mounted) indoor air quality analysis in industrial environments for such pollutants as oil mist and dust for comparison with permissible exposure levels, and have evaluated laboratory ventilation hoods and HVAC equipment for proper air flow and balancing in accordance with the requirements of American National Standards Institute/American Industrial Hygiene Association (ANSI/AIHA) Standard Z9.5  and Standard 62 of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), respectively.

eNVIRONMENTAL COMPLIANCE AUDITING

ISO 14001 is an internationally-accepted specification for an Environmental Management System (EMS). It specifies requirements for establishing an environmental policy, determining environmental aspects & impacts of products/activities/services, planning environmental objectives and measurable targets, implementation & operation of programs to meet objectives & targets, checking & corrective action, and management review.

The staff at Rodak Engineering has experience in conducting comprehensive environmental compliance audits to assist facilities in the development of an EMS for ISO 14001 certification. We have also conducted non-ISO audits that are tailor-made to a facility’s internal environmental policies and are instrumental in the development of future production planning.   Our audits focus on identifying current environmental issues at the facility as they relate to local, state, and federal environmental regulations and on developing strategies for future production planning to maintain  compliance with these regulations.   

RE staff have conducted pollution prevention studies at military bases in North Carolina to identify waste-generating areas and develop strategies for waste minimization.   These studies have been used by the bases to meet federal initiatives for pollution prevention and waste minimization.

RE staff also performed a comprehensive, multi-media environmental compliance audit of a major university in North Carolina.  The intent of the audit was to develop an assessment of the University’s performance respective to compliance with applicable environmental regulations and ordinances, as well as provide a foundation for development or modification of environmental strategies as they relate to future University activities and proposed environmental regulations. The results of the environmental audit were used to perform a gap analysis on areas deemed deficient or requiring additional attention.  By conducting the audit under the EPA’s self-audit policy, the University was able to disclose and correct compliance violations through systematic discovery and thereby not be subjected to economic and gravity-based penalties from EPA.

In addition to compliance auditing, RODAK ENGINEERING has experience in SARA Title III reporting, preparation of Tier I and Tier II reports and Toxic Release Inventories, Form R’s, and preparation of risk management plans for industrial facilities such as textiles, furniture manufacturers, fiber optic manufacturers and power plants. 

soil and ground water remediation

The Senior Staff at Rodak engineering has conducted numerous soil and ground water remediation projects in 30 States in accordance with differing State and Federal regulatory requirements.  Soil and groundwater remediation technologies implemented by the staff at Rodak Engineering include pump-and treat systems, in situ shallow and deep-zone air sparging and soil vapor extraction, dual-phase extraction, and in situ chemical oxidation (see below).

COMPLIANCE SUPPORT FOR Brownfields PROPERTIES

Brownfields are properties that are underutilized or economically abandoned sites where the redevelopment or reuse of the property is hampered by the presence of hazardous contaminants.  Cleaning up and reinvesting in these properties increases local tax bases, facilitates job growth, utilizes existing infrastructure, takes development pressures off of “greenfields”, and both improves and protects the environment.  EPA's and the respective state Brownfield Programs provide a mechanism for states, communities, and other stakeholders in economic redevelopment to work together to assess, clean up, and reuse these properties.  The Brownfields Revitalization Act of 2002 expanded EPA's assistance by providing new tools for the public and private sectors to promote sustainable brownfields cleanup and reuse.

Rodak Engineering staff has assisted in the performance of compliance assessments to support re-development of Brownfields properties.  Our compliance support activities have included an evaluation of a Brownfield facility’s HVAC system to demonstrate compliance with ASHRAE Standard 62 (proper balancing of fresh/recycled airflows), and preparation of work plans to describe assessment and remediation activities of additional areas of contamination detected within a Brownfields facility.

UNDERGROUND INJECTION

Rodak engineering staff have developed corrective action plans using underground injection of chemicals to oxidize VOCs or carbon sources to enhance the biological breakdown of the VOCs.  Chemicals such as hydrogen peroxide, Fenton's Reagent, potassium and sodium permanganate, sodium persulfate, and slow release oxygen compounds are used to oxidize the organic compound.  The biological process of anaerobic reductive dechlorination is enhanced by the addition of carbon sources such as molasses, sodium lactate, or emulsified vegetable oils.   Rodak Engineering is investigating and incorporating innovative ways of combing underground chemical injection with more conventional methods of dynamic remediation such as in situ air sparging to expedite cleanup of sites with petroleum contamination.

Staff Personnel have permitted and are currently operating a chemical oxidation process for petroleum hydrocarbon contamination using potassium persulfate in conjunction with an air sparge/soil vapor extraction system at a site in Raleigh, North Carolina, and are planning a dual remediation approach at a petroleum contaminated site in western North Carolina using deep and shallow air sparging in conjunction with underground chemical injection.
