The Office of the Inspector General (OIG), Audit Division, has completed an audit of the proposal by the Corrections Center, Nassau County, New York (County), for an Intergovernmental Service Agreement (IGA) with the United States Marshals Service (USMS). The County proposed a daily prisoner rate of $185.98.
We reviewed supporting documentation of the proposed costs on the Cost Sheet for Detention Services (Form USMS 243) received from the County to provide detention space at the jail for federal prisoners. We analyzed the daily average inmate population and daily prisoner rate were accurate and reasonable.
Based on our review, we determined that the proposed daily prisoner rate should be reduced from $185.98 to $142.32. We based this on the County’s proposed expenses used to calculate the prisoner day rate being overstates by $7,702,722, and the estimated daily average population being increased from 1,520 inmates to 1,838. This resulted in costs questioned totaling $1,593,590.
