Earlier this year American Society of Plumbing Engineers released public review draft of its consensus product — ASPE 63 Rainwater Catchment Systems. The scope of this standard covers requirements for the design and installation of rainwater catchment systems that utilize the principle of collecting and using precipitation from a rooftop and other hard, impervious building surfaces. This standard does not apply to the collection of rainwater from vehicular parking or other similar surfaces.

That is all we see from ASPE on this and other standards; most likely owing to the pandemic. ASPE typically posts its redlines in ANSI Standards Action and on the landing page for its standards development enterprise:
Note that many of its products are co-developed with NSF International, IAPMO and the American Rainwater Catchment Systems Association, among others. It is noteworthy that ASPE provides a detailed description of the User Interest; which enlightens understanding of the lamentable presence of the User Interest, thus the raison d’être of Standards Michigan.
