Scott Environmental Technology Division
SOURCE AND AIR EMISSION TESTING

Under contract with U.S. Environmental Protection Agency, the Scott Environmental Division of INTEX developed many of the reference source testing methods now required, including Methods 7E, 18, 23, 25 and 110, which are designed for the trace level detection of organic compounds. In fact, Scott Environmental personnel received nationwide recognition for the development and application of sampling and analytical methodologies for part per trillion concentrations of chlorinated dibenzo-p-dioxins, dibenzofurans, chlorophenols, aldehydes, chlorobenzenes, and polychlorinated biphenyls. The Modified Method 5 (MM5) sampling developed during this study is now one of the prescribed methodologies for the testing of hazardous waste incinerators.

Scott Environmental has the expertise and the necessary equipment to conduct source testing using most EPA Reference Methods, NIOSH, and ASTM standard methods. Literally thousands of tests have been performed worldwide for both private industry and the government.

Services


CONTINUOUS EMISSIONS MONITORING

Comprehensive CEMS Program, County WPCP
Scott Environmental designed, fabricated, installed, and certified seven O2 and NOx CEM Systems at 2 water pollution control plants (WPCP). The systems were installed on Cooper Bessemer Engines fueled primarily on digester gas. At one plant four of the CEMS are designed to sample alternate streams therefore serving as a backup to each other. The data acquisition systems were designed with extensive signal recording capabilities monitoring fuel types and other factors besides pollutant concentrations.

Comprehensive CEMS Program, Steel Mill
Designed, fabricated, installed, and certified four O2 and NOx CEM Systems at a steel mill. Three of the systems were installed on boilers and shared a common data acquisition system. The systems backed each other up by being able to sample any one of the sample paths. The forth system was installed at a coke oven works. Special design measures had to be taken to account for the severe corrosive atmosphere.

Comprehensive CEMS Program, Pharmaceutical Manufacturer
Scott Environmental designed, installed and certified an O2, CO, and opacity CEM System at a Pharmaceutical Manufacturing Plant. The unit is installed on a pathological incineration system. The data acquisition is designed with lockout controls which would prevent further loading of the incinerator if an exceedance of a specific parameter is recorded.

Comprehensive CEMS Program, Public Sewage Treatment Facility
Designed, installed and certified an O2 and total hydrocarbon (THC) CEM System at a sewage treatment plant. The unit is installed on a sewage sludge incinerator and complies with the 40 CFR Part 503 regulations. Monitoring requirements include correction for moisture utilizing two oxygen analyzers, one measuring on a wet basis, one measuring on a dry basis. The reporting package was specifically designed to meet Part 503 regulations.

Source Sampling Engines for Gas Transmission Company
Scott Environmental completed a test program for a major gas transmission Corporation. The testing was conducted at numerous locations in a three/four state area. Scott Environmental's mobile continuous emissions monitoring stations was used to measure emissions from numerous engines. The scope of testing also required on-site GC analysis.

RCRA Hazardous Waste Incinerator Trial Burn Testing, Oil Refinery
A RCRA hazardous waste incinerator trial burn test was conducted on a fluidized bed type unit used to incinerate refinery waste. Two POHCs were selected in order to evaluate the minimum destruction and removal efficiency. In addition, two separate types of waste streams were evaluated.

Because the incinerator was an older unit, prior to trial burn testing, Scott Environmental conducted a combustion study to identify optimum operating conditions. By utilizing analytical instrumentation that provides continuous analysis of exhaust gas constituents, ideal combustion conditions were identified. This approach saved the refinery substantial revenues.

RCRA Hazardous Waste Incinerator Trial Burn Testing, Agricultural Chemicals Manufacturing Facility
A comprehensive emission testing program was conducted in conformance with RCRA incinerator testing requirements. The testing program was developed to demonstrate that the hazardous waste incinerator, in conjunction with the associated exhaust gas cleaning and scrubbing equipment, could achieve a minimum destruction and removal efficiency (DRE) of 99.99% as required by RCRA regulations.

Several different waste streams were fired as part of the testing program. Applicable EPA Reference Test Methods together with the volatile organic sampling train (VOST), were used to show compliance with required principal organic hazardous constituent (POHC) destruction and removal efficiencies and particulate and hydrogen chloride emission limitations. In addition to emissions testing, a complete RCRA Part B Trial Burn Plan was prepared for the client.

ASBESTOS/LEAD/INDOOR AIR QUALITY

Air Monitoring for Complete Abatement, Manhattan Psychiatric Center
Scott Environmental was selected by the NYS Facilities Development Corporation and CRSS to perform air monitoring and project management for the complete asbestos abatement of Building 102B at the Manhattan Psychiatric Center. The site consisted of 2 sub-basements, 1 basement, 18 stories and a penthouse. This project was finished ahead of schedule and under budget.

Due to Scott Environmental's effective project management, thousands of dollars in change order items were rejected. For their efforts, Scott Environmental has been awarded a term contract with the facility to perform all of their environmental consulting services as they pertain to asbestos, lead and indoor air quality.

Air Monitoring, Marathon Battery Company
IT Corporation selected Scott Environmental to provide several services including: a site specific health and safety plan; certified industrial hygiene services; asbestos assessment; a scope of work; air and project monitoring and sample analysis for an asbestos debris clean-up project. This site was listed as a Superfund site containing lead, cadmium, and asbestos, and required entry and exit physicals for all personnel.

Scott Environmental was selected over other firms because of its ability to provide the certified personnel and insurance required to satisfy strict Federal Superfund guidelines. These guidelines were enforced by the Army Corps of Engineers, and Scott Environmental was able to complete the job well within the prescribed regulatory parameters. 180 cubic yards of asbestos contaminated soil was remediated from an 800 square foot area.
