Hey there,
By default WordPress really only creates these .htaccess rules.
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
Anything else is not standard WordPress stuff. In your example, like ExpiresByType or RewriteRule ^(.*)$ /wp-content/endurance-page-cache/$1/_index.html [L] is caused by plugins. Most likely by the endurance-page-cache plugin, which appears to be one installed on BlueHost, see https://github.com/bluehost/endurance-page-cache.
In this case, I suggest you to talk to your host about it.
In the future, the WordPress.org support forums at wordpress.org/support are better suited for questions like these.
Cheers!
