What is a Five Year Review?• Required when waste material is left in place
• EPA comes back to look at site and remedy every 5 years
• Ensures that remedy is working as designed
• Identifies any potential issues
• Evaluates new policy

Findings
• Warning liner location should be tracked and reported as
development and disturbance occurs.
• Establish routine inspection of surfaces that act as cover to
prevent exposure.
• Routine reporting on by the PRP to EPA regarding permit
requests with City of Portsmouth Permitting authority should
be reported annually.
• The site repository should be updated with recent site
documents, including recent FYRs.

Findings (2)
• During the 1997 design and implementation phase of the
remedy, four flush-mounted monitoring wells were installed.
Ensure proper well abandonment.
• City Ordinance 1996-56 coverage includes the area bounded
by Race Street to the north and Fifth Street to the east;
however, those roads do not intersect. The 350-foot radius from
the corner of Seventh and Wavy Street included in the definition
does not intersect either of those streets. EPA will evaluate if
the ordinance's boundaries are clear and effective.
