H.Amdt.18 - An amendment numbered 3 printed in Part A of House Report 115-2 to require an agency to include an economic assessment or a summary of it when an agency certifies that a proposed rule will not have a `significant economic impact on a substantial number of small entities' under the Regulatory Flexibility Act. This will ensure an agency's decision to certify a rule and not conduct a full regulatory flexibility analysis is supported by data.
