Yes LPFM stations can have translators, maximum 2. The loophole is they can lease all the translators they choose.
One LPFM broke off their programming to a separate service to place it on other non-LPFM stations. In fact there is one with several translators, a few full power and the original LPFM afforded them by separating the entity from the LPFM itself. Interestingly all are operated non-commercially and are considered a regional public broadcaster. By separating programming from the LPFM they became in essence what any satellite delivered format might be. The LPFM is technically an affiliate. The programming entity has leased and owned and operated full power stations.
For a comparison, a church might have a LPFM that carries EWTN programming that can be heard around the nation on commercial and non-commercial frequencies and LPFM stations. EWTN is simply a programming service. EWTN can legally own full power stations and they can lease or own translators. Except in certain circumstances, anyone can own a translator and then lease it to a station that can legally retransmit their signal. Several AM stations facing no available channels choose to lease a translator from a translator owner.
In the case of WOLD-LP, they may have leased or applied for a translator. Perfectly legal.
