    <SUBJECT>What tools are available to help prepare and report emissions data?</SUBJECT>
    <P>We urge your State to use estimation procedures described in documents from the Emission Inventory Improvement Program (EIIP). These procedures are standardized and ranked according to relative uncertainty for each emission estimating technique. Using this guidance will enable others to use your State's data and evaluate its quality and consistency with other data.</P>
