TAILIEUCHUNG - Process-Based Self-Assessment Tool for the Organic Chemical l Industry: EPA Office of Compliance Chemical Industry Branch

Difficulty in addressing contamination in low permeability soils may be alleviated to some degree by controlled pneumatic or hydraulic fracturing of the soil. However, engineered hydraulic fractures generally cannot be spaced more closely than about 5 feet, which means that chemical oxidants must still penetrate a substantial thickness of low permeability soil to come into contact with the contamination. Deep soil mixing with large diameter drill augers is the most effective method currently available to increase contact between adsorbed contaminants and the oxidants. In any case, long term post-injection monitoring of contaminant levels in groundwater is critical to evaluating the success of putting Fenton's Reagent into. | United States Environmental Protection Agency Enforcement and Compliance Assurance 2224A ECDIC-1998-092 ẴEPA Process-Based Self-Assessment Tool for the Organic Chemical Industry EPA Office of Compliance Chemical Industry Branch Printed on paper that contains at least 20 percent postconsumer fiber. Background The organic chemical manufacturing industry is subject to numerous Federal regulations that have been enacted to protect human health and the environment. A complex web of requirements results from the fact that little correlation exists among regulations that target the same medium or activity. Industrial facilities are responsible for understanding and complying with these requirements. Historically EPA has relied on a command and control approach to regulate industrial facilities but now is combining its traditional method with innovative compliance assessment techniques such as self-assessments and facility management systems. Many industrial facilities have found that using a complete facility Environmental Management System EMS approach uncovers cost effective solutions for tackling all the requirements as a whole instead of as individual components. In line with this discovery EPA is encouraging self-assessments as part of a complete facility EMS approach to evaluate compliance with environmental regulations. A facility s drive to identify cheaper more effective ways to achieve compliance is consistent with EPA s mission of clarifying and simplifying environmental regulatory control. Purpose of document This guide is a resource on Federal environmental regulations for small- to medium-sized organic chemical manufacturing facilities. The purpose of this manual is two-fold 1 to provide a general approach for performing a multimedia self-assessment to evaluate compliance with environmental regulations and 2 to provide industry-specific process and regulatory information necessary for conducting an assessment at an organic chemical manufacturing facility. .
