Footnotes change the application
TS ISO 46001 is not required at the first green application under the Annex 4 footnotes, but is mandatory at renewal. Rainwater harvesting refers to the relevant Planned Areas Zoning Regulation provision. Greywater criteria in the relevant tables apply to areas newly designed as of publication. The municipal treated-effluent reuse criterion and its population footnote must also be read together.
