I think you should consider at least posting a link to the BCAPL rules.
Also, I note that you refer to WPA and "BCA" rules as being one in the same. That is only true in the sense that the BCA (Billiard Congress of America) publishes the WPA rules in their book. However, the BCA is not responsible for the content of, nor produces or edits in any way, the World Standardized Rules produced by the World Pool-Billiard Association.
Also please note that the BCAPL is not associated with the BCA, other than in the sense that they are a member of the BCA. The BCA does not own or regulate the BCAPL in any way, and the letters "BCA" in BCAPL do not stand for "Billiard Congress of America", nor anything else. They are simply letters.

Find the Official Rules of the BCA Pool League here:
* The contents of this post refer to BCA Pool League (BCAPL) Rules only. The BCAPL National Office has authorized me to act in an official capacity regarding questions about BCAPL Rules matters in public forums.
* Neither I nor any BCAPL referee make any policy decisions regarding BCAPL Rules. Any and all decisions, interpretations, or Applied Rulings are made by the BCAPL National Office and are solely their responsibility. BCAPL referees are enforcers of rules, not legislators. BCAPL Rules 9.5.3 and 9.5.4 apply.
* No reference to, inference concerning, or comment on any other set of rules (WPA, APA, VNEA, TAP, or any other set of rules, public or private) is intended or should be derived from this post unless specifically stated.
* For General Rules, 8-Ball, 9-Ball, 10-Ball, and 14.1 Continuous: there is no such thing as "BCA Rules" other than in the sense that the Billiard Congress of America (BCA) publishes various rules, including the World Pool-Billiard Association's "World Standardized Rules" for those games. The BCA does not edit, nor is responsible for the content of, the World Standardized Rules. The Official Rules of the BCAPL is a separate and independent set of rules and, to avoid confusion, should not be referred to as "BCA Rules".
* Since 2004, there is no such thing as a "BCA Referee". The BCA no longer has any program to train, certify or sanction billiards referees or officials.
* The BCAPL has no association with the Billiard Congress of America other than in their capacity as a member of the BCA.
* The BCAPL has not addressed every imaginable rules issue, nor will it ever likely be able to, as evidenced by the seemingly endless situations that people dream up or that (more frequently) actually happen. If I do not have the answer to a question I will tell you so, then I will get a ruling from the BCAPL National Office and get back to you as soon as I can. If deemed necessary, the BCAPL will then add the ruling to the "Applied Rulings" section of The Official Rules of the BCA Pool League.
