2. Motivation The complexity, diversity, and volume of federal and state regulations: are detrimental to business increase the risk of companies failing to comply with environmental regulations hinder public understanding of the government

3. Background Current state of compliance checking: Paper-based process Locating and interpreting the relevant regulations is complex, even with the help of supplementary information Small companies have difficulty conducting compliance checks due to lack of resources and knowledge Vision for future: Up-to-date regulations and compliance-checking assistance procedures available online Improved regulation and compliance requirement transparency through clear presentation and linking

Rule logic represents the rules specified by the regulation: 40.CFR.279.12.b – Use as a dust suppressant: The use of used oil as a dust suppressant is prohibited… Option elements define the user interface: Is the used-oil used as a dust suppressant? (usedOil(oil1) & dust_suppressant(oil1)). (usedOil(oil1) & (-(dust_suppressant(oil1))). Control statements specify processing instructions for compliance-checking:
