If the motion meets the required threshold, the governing body must call the EGM within 21 days. However at least 93 clubs will be needed to attend on the day to ensure the meeting is valid.
But the WRU has said the proposed motions would reverse hard-won progress, stall vital investment and jeopardise the prosperity of Welsh rugby at every level.
It claimed £28m of planned investment in the game would be delayed, thus “undermining long-term success” on the field and impact preparation for the Six Nations.
Financial and commercial stability, as well as governance integrity, would also be in jeopardy, it claims, that would “drag Welsh rugby back to outdated structures and a return to debilitation factional internal politics”.
Instead, the Union has urged clubs to raise issues with elected WRU council or board members.
