Anything on the border of the U.S. and touching the correct county was reassigned an accuracy of 4. An accuracy code value is equal to 3 if the point is outside the associated state border but still inside the U.S. borders. Anything on the point's associated state boundary and touching the correct county was also given an accuracy of 4. The state coverages were also checked against each other to ensure data format consistency throughout the country. EPA would be appreciated.
