Here's what the vatican has to say:
[quote="http://www.vatican.va/archive/ENG1104/_P4O.HTM]Can. 1251 Abstinence from eating meat or some other food according to the prescripts of the conference of bishops is to be observed on ,of abstinence binds those who have completed their fourteenth year of age. The law of fasting, however, binds all those who have attained their majority until the beginning of their sixtieth year. Nevertheless, pastors of souls and parents are to take care that minors not bound by the law of fast and abstinence are also educated in a genuine sense of penance.
Can. 1253 The conference of bishops can determine more precisely the observance of fast and abstinence as well as substitute other forms of penance, especially works of charity and exercises of piety, in whole or in part, for abstinence and fast.
So it would seem to me that the USCCB has the authority here.

so instead we have a church division between catholic.org and usccb.org
Curiously, the webpage: catholic.org/clife/lent/abfast.php you linked to listed these same canon laws recognizing the authority of the conference of bishops. So no, no division in the church. I don't know why they provide this strict interpretation of fasting and abstinence guidelines.

so they should not be considered to hold any authority. (I'm not trying to undermine the value of their work, mind you)
I may be mistaken, but I believe each individual bishop is not strictly bound by the decisions of the conference. Therefore, you may decide to contact the office of your bishop and request that they clarify the abstinence of meat for your diocese.
