The new ordinances set noise limits, times tests can be performed, limits on the size of rocket motors that can be tested and limits on vibrations the rocket motors can produce.
Fees payable to the city can reach as much as $50,000 per test if the rules are not adhered to.
The ordinance establishes the Rocket Motor Testing Zone, which is the area within one mile of the center point of the zone.
The restrictions on sound are established within three miles of the center of the City of McGregor.
For a test whose volume exceeds 115 decibels, the city requires a permit that includes payment of $5,000 for each test.
For a test that exceeds 120 decibels, the city requires a permit and a payment of $7,500 per test.
For a test that exceeds 125 decibels a permit and payment of $50,000 is required, the ordinance says.
The ordinance also establishes a requirement that the city be allowed to inspect the facility to ensure that the company is adhering to the new requirements.
The ordinance also limits acceptance tests to 15-seconds or less and says that if noise limits of 125 decibels are exceeded, the test must be curtailed within 3 seconds.
Testing also is generally restricted between the hours of 9 p.m. and 7 a.m. and all tests involving a rocket motor that generates 2 million pounds of thrust must be conducted during daylight hours.
