New Practice for Laboratory Performance Verification of Hydrodynamic Separators for the Treatment of Stormwater
1. Scope
1.1 This practice covers the criteria for the laboratory verification of hydrodynamic separators (HDS) as it relates to the removal of total suspended solids (TSS) in stormwater runoff. 1.2 These manufactured treatment devices are placed as offline or inline treatment devices along storm drain pipe lines to remove stormwater-borne solids. These devices may be used to remove other pollutants that are not covered in this practice. The criteria in this practice relate to the removal of silica particles in controlled laboratory conditions. 1.3 This practice provides guidelines for independent verification entities to streamline programs that certify and accept the use of these devices within their justification. For a specific verification entity, other criteria may apply. 1.4 Units--The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversion to SI units that are provided for information only and are not to be considered as standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Rationale
Currently, no unifying pratice exists for guiding the prcocess by which stormwater treatment systems are evaluated.
The title and scope are in draft form and are under development within this ASTM Committee.
