I don't see how; there are really no show stoppers on the list, just precautions to preserve reasonable public access to the beach and mitigate light and noise pollution, as well as make sure SpaceX is taking the proper care to respect the historical and natural landmarks in the area.
Unless I missed something, the technical challenges of launching Starship remain the long pole in the tent.

I agree with Robert. Given the scale of what SpaceX is trying to do the regulatory "burden" placed upon SpaceX is minimal. For anyone that is aware of the inner workings of large scale development projects this is almost a "get out of jail free" card.
The assorted species biological protections make good logical sense, and are not particularly difficult to do. While Cape Canaveral/KSC did not have significant environmental laws when they were first developed, you can bet your bottom dollar that biological protection of the area has become much more restrictive over the years, thanks in part to the "Earthrise" photo of Apollo 8.
As an aside, if you actually read the 40 page report in the link, it is amusing to see how some of the interest groups were bought off for absolute chump change... $5,000 here and there... for "free" fishing tackle etc.
To me perhaps the biggest constraint placed upon the project is the 500 hours per year closure limit on the highway, with, up to, another 300 for "anomalies." It would not surprise me, that if SpaceX has made it safely through a given year with no major anomalies, that they may claim some in December, to add some extra hours for highway usage.

Has a study been conducted on the effects of an exploding, fully fueled Super Heavy booster on the area surrounding Pad 39A at KSC? Could debris from such an event damage the Pad 39B launch site as well?
I might also be concerned that a launch or landing mishap involving the Super Heavy booster might take out the Falcon 9 launch pad facilities and there would be no place from where to launch manned Dragon flights.
I guess that I do not have a clear understanding of SpaceX's launch facilities plans at KSC.

My guess is your question(s) stem from the Reuters report of a week ago that NASA wants SpaceX to ensure its plan to launch Starship from Florida will not put at risk the infrastructure needed to supports Falcon 9 flights to the International Space Station.
"We all recognize that if you had an early failure like we did on one of the early SpaceX flights, it would be pretty devastating to 39A," Kathy Lueders, NASA's space operations chief, said in an interview of the agency's discussions with SpaceX.
SpaceX did not return a request for comment.
SpaceX has already invested heavily in building a Starship pad some hundreds of feet from pad 39A's launch tower. It has responded by pitching NASA on a plan to outfit its other Florida pad - Launch Complex 40, five miles away on Space Force property - with the means to launch U.S. astronauts, according to a person familiar with the plans.
The company is also studying ways to "harden" 39A, or make the launchpad more resilient to both an explosive Starship accident and the immense forces emitted from a successful Starship liftoff, Lueders said.
Hardening the 39A pad and launching humans from pad 40 would both require agency approval.
"SpaceX is working with us on those things," said Lueders. "Because it's also in their best interest to not have what is a pretty steady source of income for them become interrupted."
The reality is SpaceX is a year (or more likely, more) away from being ready to launch Starship from Pad 39A, so there is time to address NASA's concerns and take precautions as necessary.

I wish SpaceX well with their upcoming test launches. I fully expect the first several to go Boom, but I hope that SpaceX figures out the issues and gets the Super Heavy/Starship combo working properly.
What SpaceX is attempting to do is truly mind boggling, and I hope they are successful in bringing this rocket to full commercial success.

SpaceX completed a seven engine static fire test with its Super Heavy Booster 7 at Starbase in Boca Chica, Texas on Monday (Sept. 19).
Booster 7 now returns to high bay for robustness upgrades and booster 8 moves to pad for testing.
Next big test is probably full stack wet dress rehearsal, then 33 engine firing in a few weeks.

SpaceX is starting work to host cargo and crew Falcon 9 launches from Space Launch Complex 40 at Cape Canaveral Space Force Station, SpaceNews reports.
At a Sept. 26 briefing, Bill Gerstenmaier, SpaceX vice president for build and flight reliability, said the company had already started preparations for the upgrades needed at SLC-40 for cargo and crew launches. "We've already started the work to begin the preparations for pad 40. We've ordered some hardware, put some contracts into place," he said.
He didn't elaborate on the work needed to prepare SLC-40 for cargo and crew missions. "We'll do cargo first. We can do that fairly easily," he said. "It gives us some flexibility to move some things off 39A, which helps us balance launches off both pads. We'll add crew at the right time."

SpaceX will attempt a static-fire test of all 33 engines in its Starship booster as soon as Feb. 9, a test that could allow the company to attempt an orbital launch a month later, reports SpaceNews.
Speaking at the Federal Aviation Administration Commercial Space Transportation Conference here Feb. 8, Gwynne Shotwell, president and chief operating officer of SpaceX, announced the impending test, the final major technical milestone before the vehicle's first orbital launch attempt.
"Tomorrow is a big day for SpaceX. We are going to attempt a 33-engine static fire booster test for Starship," she said. "It's really the final ground test that we can do before we light 'em up and go."

I'm assuming that on a real launch attempt, the need to shut down one of the engines before ignition would result in a launch abort, but would the same apply if one of the engines shuts itself down between ignition and liftoff?

According to Elon Musk's tweet (see above), even with two engines out, there were "still enough engines to reach orbit," so what the launch rules will be or when an abort might be called is still to be seen.

Yes, I saw that tweet, but I'm pretty sure he meant that if the vehicle lost two engines AFTER lift-off, it would still have enough thrust to make it to orbit. After all, Apollo 6 made it to orbit, but I'm betting if NASA had known in advance they would lose an S-II engine (even excluding the issue over the second engine) they would have aborted the launch.
I suppose the key question is what the launch rules will be. I just can't see the Super Heavy launch going ahead if even one engine signals that it's faulty before ignition, or shuts down after ignition but before liftoff. Of course, we can't really look to the Saturn V for guidance on that: the Saturn V couldn't lift-off on four engines. Maybe 32 out of 33 will be acceptable for Super Heavy.
If you get any insights into the SH launch rules, Robert, please let us know!

Intent is fill the rocket and ignite all 33 engines
But only fill 1/3 full
And one engine does not light
And one engine shuts itself down in the 5 seconds of the test
Well, you’ve learned a lot but it stretches the definition of success.

With respect to Mr. Hale, we don't know that the intent was to fully fuel the rocket. In my mind, it might be best not to, in the case that something went massively wrong, and you wanted to limit the size of the fireball. Plus, that fuel isn't cheap.
If SpaceX's launch rules are such that a single engine problem just before launch doesn't warrant an abort, then this test was indeed a success. If they aren't comfortable with the results, I would assume we'd see another static fire before the orbital test flight.

Federal Aviation Administration (FAA) release
FAA Issues SpaceX License to Launch Starship/Super Heavy
On April 14, the FAA issued SpaceX a Vehicle Operator License to launch the Starship/Super Heavy vehicle from Boca Chica, Texas. After a comprehensive license evaluation process, the FAA determined SpaceX met all safety, environmental, policy, payload, airspace integration and financial responsibility requirements. The license is valid for five years.
The FAA is responsible for protecting the public during commercial space transportation launch and reentry operations. We carefully analyzed the public safety risks during every stage of the mission and required SpaceX to mitigate those risks.
In addition, the FAA will implement various airspace integration measures designed to reduce the impact of the launch on commercial airline flights and other airspace users.
The FAA will use key mission "triggers" such as the loading of rocket fuel and the final disposition of the booster rocket to pinpoint when to close and reopen airspace.
For the first time, the FAA will implement time-based procedures for a launch from Boca Chica. This will identify and reroute only the aircraft directly affected by the closed airspace allowing more aircraft to stay on their most optimal and efficient routes. It has previously only been used for launches from the Florida space coast.
Both the Starship vehicle and the Super Heavy booster rocket will transmit telemetry data to the FAA via the Space Data Integrator tool. Data such as position, altitude, speed and any deviation from its expected flight path will provide the FAA situational awareness, and in combination with other information, help to reopen airspace quicker.
