I'm assuming you asked for a clarification, this may be a dead issue (if so, please tell us), but let's unpack the terminology in the hopes that this helps someone who is starting out and has a similar question.
Standard Operating Procedures are just what they sound like: the specific way that a task is to be performed while conducting business. Any time you have a document is of the topic "what to do when _____ happens", and you have a set of structured tasks, then you have a SOP. These tasks should all be reduced to writing and may depend on each other e.g. if we were talking about restaurant SOP's, perhaps we would have one for taking a food order, making the food, and a third for delivering the food to the customer. Although some might argue that these things are obvious, I've found it in my experience best to not assume.
Most commonly, there are SOP's by department. Off the top of my head, I think of shipping/receiving SOP's, Production SOP's, Maintenance SOP's, and Sanitation SOP's, and personal hygiene SOP's, and even Security SOP's. The financial and HR departments, not to be outdone, have their own SOP's, most of which are probably unknown to anyone outside of their departments.
Because you mentioned the words "scheduled" and "facility", I would guess they could be referring to are Maintenance and Sanitation SOP's, as these both have tasks that aren't necessarily performed every day, and those scheduled tasks have the potential to speak volumes about how mature a program is and how many resources are dedicated to the department.
