Documentation of Remediation

We have a site we know to be contaminated and we are undertaking a remediation plan. In the LEED Reference Guide under SSp2-Documentation it says that documentation is required from the governing authority stating that remediation standards have been met. In the LEED Online Template they request documentation from either the environmental consultant or a governing authority. We would prefer to use documentation from our environmental consultant. Has anyone submitted without documentation from a governing authority?
