Stockpile Sampling Frequency - Ontario Regulation

Information Last Updated - November 17, 2016

In accordance with Ontario Regulation 153/04 (as amended), there is a table as follows:

Table 2 - Minimum Stockpile Sampling Frequency



Typically, this stockpile regulation is used for on-site material that will be re-used on the Record of Site Condition (RSC) property. 

Consultants tend to reference this table when looking for a guideline to standardize a sampling frequency for stockpiles. 

It is not uncommon for clients to request fewer samples.  It is the obligation of the receiving site to ensure the quality of the material before it is transported to them.
